Alteration of a trimmer for grass in the boat motor

First of all, you should pay attention to the size and power of the engine. So that the feed of the boat does not fall under water, you can not use too heavy devices. Easy to maintain and have light weight of two.stroke models

Four.stroke options are installed on large boats

Easy to maintain and have light weight of two.stroke models. Four.stroke options are installed on large boats.

Power

High.power engine can turn the boat over the start. So that this does not happen, you need to know what power the device should have. A motor 8–9 liters are installed on a boat up to 7 m in size. With. For a small boat 5 m long, an engine with a power of up to 5 liters will be enough.With.

Work voltage

There is a flywheel with magnets on the motor. The flywheel consists of the ignition coil and core with a wire. The ignition coil is powered by electric current, which is formed inside the core wire. From the reel, the current comes to the candles. The generator coil installed under the mossy produces a voltage of 6-40 V, and the operating voltage of the engine should be 12 V. The installed regulator helps to fix the situation. Когда обороты двигателя увеличиваются, возникающие скачки напряжения поглощаются аккумулятором.

Gearbox and its impact on work

The corner gearbox for the boat engine is a separate node that works together with the electric motor. The unit is light and has compact dimensions. But, despite these data, he has a large efficiency and is able to do a lot of work. The attachment of the gearbox will help reduce the frequency of rotation, as it converts the existing energy to the mechanical and transfers it to the output shaft. In this case, the transmission of the torque will remain high.

We make an adjustable electric type from a drill

Many sufficiently enterprising fishermen have an idea to create their own electric motor from a drill or from an electric screwdriver. Their feature is that they also carry out their activities on batteries, as well as industrial samples. To make such a device yourself, the layout for this unit will always be the same:

  • As a power source, you need to take the battery;
  • An electric motor will act as an engine;
  • To move in the future, it is necessary to take a rowing screw equipped with a gearbox in the future;
  • The control unit will make it possible to turn the boat during movement and monitor the speed of control of the electric motor.

All these elements that are required to create such a motor can easily find in an electric screwdriver or a drill. If you decide to use an electric drill, then in the future you must worry that it is located as far as possible from the surface of the water. If water gets at least in a small quantity to the control unit, then this can immediately stop the boat during movement in the middle of the reservoir.

To make an electric motor from a drill or an electric screwdriver, it is important to take care of the preparation of such important tools and elements as:

  • scissors designed for metal threads;
  • set of drills and electric drill;
  • welding device;
  • grinding and cutting circles along with corner grinding;
  • For the motor, you need to purchase an electric drill;
  • To fix the engine, in the future, co.manufacturing clamps or factory type are needed;
  • To fix the motor on the so.called boat transkom, you can take a gearbox from a device such as an angular grinder;
  • tubes designed to connect the motor and create a bar;
  • A metal round rod, which will subsequently be used for the motor shaft;
  • For a rowing type screw, you can take sheet metal.

How to make a boat motor with your own hands from a trimmer for grass?

To assemble a motor from a trimmer for grass to a boat, the manufacturer will need to prepare the following equipment and materials:

  • household lawn mower;
  • clamp. If it is not, then you can use any other mount for reliable fixation of the motor on the boat;
  • a sheet of duralumin, the thickness of which should not be less than 2 mm;
  • welding machine;
  • set of fasteners;
  • set of screwdrivers and wretched keys.

To assemble a home.made rowing screw, the manufacturer will need drawings. They should indicate the exact dimensions of the blades and the method of fixing them on the axis.

It must be remembered that the lower the power of the drive used and the mass of the boat, the less should there be a blades. For example, a screw with blades 10 × 3 cm is suitable for a boat with a mass of not more than 120 kg.

After the preparation of equipment and a thorough study of drawings, you can start assembling homemade.

The work algorithm should look as follows:

  • First of all, the manufacturer will need to finalize a bent shaft. First you need to dismantle the factory nut placed in a bobbin with a pre.wound fishing line. The nut itself in shape resembles a small 2-centimeter tube with internal thread. If necessary, it can be divided into 2 small full.fledged nuts. During the dismantling of fasteners, you need to be extremely careful so as not to lose them. If this happens, then finding another suitable fastener can no longer work;
  • After dismantling the nut, you will need to dismantle the plastic pad located on the gas button. There are no roller bearings at the end of the standard curved rod. They are replaced by an ordinary bronze sleeve, which is often called a sliding bearing. It needs to be gently extracted. Before this, you will need to unscrew the nut, as well as remove the daily and metal shafts from the tube;
  • Then you need to go to knocking out a plastic tread located on a flexible shaft. In the future, the steel pipe can be thrown away, since it will not be possible to align it with improvised means. It can be replaced by a duralumin pipe with the same diameter. It will need to install a bronze sleeve, which will need to be moved by a canvas using a hammer. Next, you need to take a plastic tread pre.trimmed in diameter, and install it on the pipe;
  • The next step will be the manufacture of the screw. To do this, you need to cut out duralumin blades and sharpen their edges. After that, each blade will need to bend up 1 cm up so that the screw step is at least 10 cm. You can fix the finished device using a nut;
  • Next, you need to install a bicycle speed switch on the boat motor from motorcycles, which will replace the standard plastic lining. After that, you will need to install a silencer that will take the engine exhaust away from the boat driver;
  • To fix the boat engine from the lawn mower, you need to use two plywood sheets. After that, the shaft will remain using 4 screws for this. During the transportation of a boat motor from a trimmer for grass, the shaft can be removed.

After the homemade nozzle is ready, it will need to run into. To do this, prepare a fuel mixture of fresh gasoline and motor oil in a ratio of 40: 1. After that, you will need to pour the finished mixture into a standard boat engine tank, start it, and let it develop 1 full fuel tank at idle. After running in, a home.made boat motor from a trimmer for grass will be completely ready to work.

How to use a boat motor from motorcycles correctly?

Using a trimmer for grass, like a boat motor, the operator needs to constantly monitor the condition of the engine, and give him time to cool.

In addition, to extend the operating life of a boat motor from a trimmer for grass will help:

  • Checking all the mounts available in the device. before each launch of the motor, you need to carefully inspect the latches that hold the engine elements from the trimmer for the grass;
  • the engine is refueling from the trimmer for grass only with the gasoline and oil that was used for operation of motorcycles;
  • timely cleaning and replacing the air and fuel filter of the engine;
  • regular verification and timely replacement of the fuel pump;
  • inspection and, if necessary, replacing the spark plug.

The regular ventilation of its standard cylinder will also help to extend the operating time of the boat ICE from a trimmer for grass. To do this, about once every 2 months, you need to twist the spark plug, and it is rarely possible to pull the starter cable 4-5 times. After the procedure, the candle can be screwed back to the place and continue the operation of the engine.

Model from a chainsaw

You can assemble a model from a chainsaw if there is a ready.made deidwood. Also, the model will need a good stand. It is quite difficult to make it from the pipe on your own. Screws are most often used small in size. However, in this case, a lot depends on the power of the chainsaw. The clamp is directly recorded behind the starter. In order to protect the device from water, the casing is used.

A long stem is used to fix the rack. Sold it in an upright position. Homemade boat motors from a chainsaw with water pumps in our time are rare. It is also important to note that the clamp should be fixed along with metal corners. Some use screws or clamps for this.

What do home.made motors for boats make?

If desired, a motor for a light boat can be made independently. In most cases, ready.made tools are used as the basis.

The following is often used:

  • The grass mowel is ideal for creating a trimmer for grass. It is intended for prolonged operation, so it can last for a long period.
  • In some cases, the construction of a construction mixer is carried out. In this case, batteries act as an energy source. This version of the performance is ideal for quiet fishing, but it is not designed for prolonged use.
  • The gasoline saw is rarely used. However, its design features determine the fact that it is necessary to conduct a serious alteration.

Good to know! When choosing, attention is paid to weight and economy, as well as some other indicators. The selected device used as the basis for the boat motor should withstand prolonged operation and characterize increased reliability.

Advantages of using a trimmer for grass

Using a trimmer for grass to create a boat engine has a number of advantages:

  • much cheaper than a finished motor for the boat;
  • minimum fuel consumption;
  • low weight;
  • reliability;
  • tightness of the structure;
  • the presence of ready.made elements for control;
  • built.in tank and t.D.

Thanks to these qualities, a trimmer for grass takes first place among other options for remaking options.

Features of a homemade engine

When converting the motor, it should be borne in mind that they were developed to perform different functions. The trimmer for grass functions at large speeds and a small spinning moment, and the boat motor should do the opposite. Therefore, alteration of the device requires special tools and even a drawing.

The engine from a trimmer for grass is more convenient and easier to build, since it has a number of necessary components of the mechanisms:

  • very economical engine;
  • Impressed unpainted fuel tank, which allows you to easily control the amount of fuel;
  • the presence of a starter and gas in the device;
  • a rod equipped with a hard shaft.

It remains only to buy the missing details or make them yourself and you can start making an engine for a boat.

The trimmer for grass functions at large speeds and a small spinning moment, and the boat motor should do the opposite

What can be done

There are several possible options for finalizing a trimmer for grass for a swimming engine.

A very simple way, but requires additional financial costs.

You will need to purchase the following details:

  • Clamp for fastening the device to the boat transza.
  • Propeller screw. You can purchase a ready.made set via the Internet, since in stores such a product may not be. The configuration includes a special drive made of stainless steel, as well as universal adapters for a flexible shaft of a trimmer for grass, which allows you not to bother with the right to your lawn mower or not.

Advice! Sometimes there may be a clamp, so before buying it to clarify what is included in the kit.

The attachment drawing to the trimmer is indicated in the instructions. For installation will need about half an hour.

To remake, you will need an angular gearbox from a corner grinder, a screw that can be cut out of a sheet of stainless steel, as well as seals and bearings for fasteners. This method allows you to get maximum speed, despite the small step of the screw. In the field atmosphere, the device requires additional adjustment, which is performed using pliers.

This method is performed as much as possible. Consider it in more detail on the example of a lawn mower with a two.stroke engine with a volume of 25 cm 3. The device weighing 4.5 kg and 700 watts is equipped with a bent leg. Trimmer for grass with such power allows you to move a boat at a speed of about 5-7 km/h.

To remake, you will need an angular gearbox from a corner grinder, a screw that can be cut out of a sheet of stainless steel, as well as seals and bearings for fasteners

What is required

Materials, as well as tools, will be required:

  • Trimmer for grass.
  • Duralumin with a thickness of 2 mm. It is necessary for the screw.
  • Clamp or any other devices for fastening the device to the boat.
  • Welding device.
  • Fasteners.
  • Additional tools for work.

All the necessary elements can be bought or made independently. The drawing may be needed to develop a home.made screw, but not for the drive. The dimensions of the screw directly depend on the power of the drive, as well as on the weight of the swimming agent. For example, a screw with dimensions of 10×3 cm is able to move transport with a mass of about 120 kg.

Production instructions

To make a boat engine from a regular trimmer for the grass, you will need to perform the following actions:

In no case do not throw away and do not lose the nuts, since the developers use their own type of thread, which is not a metric or inch

To run up a home.made engine, you will need a gas tank (0.5 l.) with oil in a ratio of 1:40. One fuel tank allows you to overcome about 10 km of territory. The speed of a swimming agent with such a motor is in the range of 5.6. 7.9 km/h, depending on the load of the boat.

Fast assembly of the motor for a boat using a chainsaw

The use of the engine from the chainsaw for the manufacture of the boat engine is a very effective solution. At first, at the stage of its disassembly, it is necessary to pull out the tire and the pump that supplies the oil to the circuit, the lever that allows you to adjust the speed and the gas tank (not suitable due to the design of the motor).

Using the material of the textolite, it is necessary to make the mounting location for the main part of the engine in which the starter and the entire adhesion mechanism will be located to another part of the engine (this design will make the engine work most effective).

In the lower part of the entire structure, it is necessary to insert a sleeve of steel by the press, which will be attached to Deidwood. Daidwood will be made of an oar for an inflatable boat (costs cheaply), which is made of duralumin. The coupling responsible for the clutch should be connected through a special shaft to the gearbox.

The gearbox can be made from the components of the parts of the grinding machine. It is filled with oil used to lubricate the transmission of the car. The structure of the structure is still carried out by a clamp or a vice. The steering wheel of maneuvers can be made from the duralumin pipe (the rest of the oar).

For the handle of gas, as in the case of a trimmer, a frequency from a bicycle may act. The screw, as the main part of the motor, can be made in the same way as in the case of a trimmer, using duralumin. In this case, the calculations carried out to clarify the size of the screw remain the same.

Fans of fishing, using boats, of course, will be interested in the simplest home-made boat suspension electric motor

, self.made

Home.made boat electric motor design

It is quite simple and reliable, cheap and affordable in manufacturing. The use of such a suspended electric motor allows you to easily, without noise, maneuvering with a boat, without looking up from fishing, in particular to keep the boat in the desired position against the current.

The main elements of the installation are a 6- or 12-volt battery and, respectively, a 6- or 12-volt power engine of direct current. The battery can be used from the passenger car.

A. the shape of the rowing screw in plan (marking); B. the device of the oil seal and drain plug; 1. a shaft of a motor with a thread, rotation of the shaft (for the removal of water from the oil seal); 2. the lid of the omentum; 3. sealing ring (rubber); 4. clamping washer; 5. oil seal (felt); 6. body oil sealing; 7. intermediate clamping washer; 8. flange of the drain plug; 9. sealing ring (rubber); 10. drain plug.

The electric motor must be mounted in a hermetic casing, which can be boiled or soldered from sheet tin. To do this, you can use a canning can of suitable size. The output of the casing for the shaft of the motor must be provided with an sealing box that would ensure the tightness of the casing. One of the possible options for the design of the omentum is shown in rice. 2, b.

To drain the leaky water, it is necessary to provide in the lower part of the casing the installation of a drain plug with a thread and a sealing washer. In the upper part of the casing to connect to the steering column, weld a transition pipe with a thread.

The manufacture of other parts is not technical difficulties. The steering column is made of a water pipe with a diameter of 0.5 inches. Bend it in the form of the letter “g”. At one end, cut the thread under the casing pipe, and on the other, put the handle from insulating material. The steering column is used simultaneously to lay the wiring to the motor.

To attach the suspended electric motor to the stern of the boat, a metal clamp is used, to which the steering column bracket is welded, limiter and emphasis.

The rowing screw of a homemade suspended boat electric motor is made of sheet steel or brass with a thickness of 1.5 mm.

To fasten the rowing screw on the motor shaft, use a sleeve sleeve. Before the final assembly, the parts are carefully cleaned with the skin and paint the metal paint. Such a homemade suspension boat electric motor (without a battery) is very light and convenient.

Boat motors today are very popular. If we consider the medium.power model, then it is very compact and designed for about 5 horsepower. In design, most modifications are quite different. This is primarily due to different types of Dadvudov. Additionally, it should be borne in mind that the connected connector is affected by the device parameters. You can make an boat electric motor yourself, however, you should familiarize yourself with its device in more detail.

Ladoga lake

Boat owners are constantly experimenting and finding amazing solutions. Makes them do too much cost of industrial samples. As a result, the idea of ​​installing a gas mower was born on a boat of a motor. These are engines with a capacity of about 6 liters.With., which are designed for long.term work under load in various conditions. A similar engine can be adapted to the boat if you use various spare parts intended for the repair of Soviet boat engines.

Motor from the Ural chainsaw.2 “

Some craftsmen easily adapted motors from Soviet chainsaws, as motors for boats. A huge number of chainsaws were released at one time, the quality of which must be discussed separately. Despite this, installed on boats, some motors serve to this day. The main thing is to calculate everything correctly.

In general, it was risky to take such an engine planned a serious campaign. And two weeks before the start, a difficult decision was made to buy and quickly convert another brand brand mower. So there was a return back to the two.stroke “shindai”, only a little greater power (model Shindaiwa C230. 1.2 l.With). I managed to redo it, but rolled up on the route 🙂

Refinement of a trimmer for grass by means of a finished set

The choice of a gasoline trimmer for grass as a fundamental device for a boat engine, which is not inferior in its technical characteristics of mass-produced models, such as the “centified ml-5241rd” and others, is due to the presence of a number of nodes that do not need to be finalized. Among them:

  • an economical engine of internal combustion;
  • bar, equipped with a hard shaft;
  • motor launch mechanism (starter);
  • Unbrued fuel tank, so that there is the possibility of visual control of the amount of combustible mixture.

Choosing a trimmer for grass to turn it into an engine into a boat, you should decide on its power. For example, for a small rubber boat “Ufimka-22” a trimmer for grass with a capacity of 0.7-1.0 kW is suitable. A craft equipped with such an unit will be able to develop a speed of about 5-8 km/h. If it is necessary to set in motion a heavier boat, then a trimmer will need for the grass more powerful.

On a note! Choosing the power of motorcycles by weight and dimensions of the existing boat, it is necessary to take into account the mass of the most hinged engine.

You can turn a trimmer for grass into a boat motor in various ways. For example, you can buy a set of finished parts necessary for revision, and use the management attached to it. With it, for a short time (no more than 1 hour), you can turn the motorcycle into the engine to the boat.

The kit for the nozzles for remaking a trimmer for grass in the motor for the boat includes the following details:

  • propeller screw;
  • a special drive, which is made of stainless steel;
  • a set of adapters and nozzles for different types of trimmers (universal);
  • Control handle (room), equipped with a muffler button and a gas adjustment handle;
  • a clamp for attaching a trimmer for grass on the sausage of boats, etc.

, But the engine itself is not part of it.

Important! By mounting the components of the kit per trimmer for the grass, the owner will need to attach the gas control cable to the motor, and then fix the muffler cable, unfolding it towards the rowing screw.

Methods of independent manufacture of a boat engine from motorcycles

The easiest way to make a motor for a boat is to use motorcycles with a straight leg (bar) and, accordingly, a hard shaft. In this case, the entire refinement boils down to the production of a rowing screw, which can be cut out of the stainless steel strip or duralumin. Process size. 100x30x2 mm. The blades should be given a curved shape, for which they need to bend by about 10 mm. The edges of the screw need to be sharpened. An example of building a simplified drawing of a rowing screw is shown in the figure below.

Important! The dimensions, the number of blades and the angle of their bend are selected individually, based on the weight-gatarit parameters of the boat and the power of the engine of the trimmer for grass.

The manufactured rowing screw is installed in the place of the trimmer head. In this case, the use of a ring nozzle, which will not allow the screw to damage the boat, will be desirable. In more detail, the process of finalizing a trimmer for grass with your own hands is shown on

Finalization of the angular grinder gearbox

To achieve the maximum number of engine speeds, you can equip a trimmer for grass with an angular gearbox from an angular grinder, which must first be finalized. At the same time, seals and bearings may be needed. The process of finalizing the gearbox itself is to replace the standard short shaft with a longer trimmer bar for grass. However, for this you will have to disassemble the gearbox.

Important! The shape and connecting dimensions of the new shaft must correspond to the parameters of the node extracted from the gearbox. This, in turn, will allow the use of bearings and gear available in the gearbox.

Having made a new shaft, the gearbox is assembled, having previously protected the bearing with an oil seal, excluding the penetration of water into it. In addition, it is recommended to apply a thick lubricant on the available gears or fill the internal cavity of the case with it. For sealing the case, the rubber seal and/or sealant is used.

On a note! By increasing the speed of the trimmer engine through the gearbox, the rowing screw should be attached to the output shaft of the latter.

Trammer finalization for grass with a curved bar

If there is a lawn mower at the disposal of the owner of the boat, the rod of which is curved, the latter must be dismantled and replaced with a straight pipe of the corresponding diameter made of duralumin. If the diameter of the new tube is larger than the size of the hole in the motor unit, then the seat will need to be protected to the desired size. Revision is carried out in the following order (see. drawing).

  • First they turn out the standard nut 2, which is located in a spool with the cord. At the same time, it is strictly not recommended to throw out fasteners removed from the bar, since the manufacturers of motorcycles often use their own types of threaded joints, which do not correspond to the standard.
  • Then unscrew the standard nut 4 and remove the deedwood (pos. 8) and flexible (pos.9) shafts.
  • Then cut position 6. sliding bearing (has the form of a bronze sleeve at the end of the shaft).
  • Next, knock out a plastic tread 10 out of the rod.
  • In a previously selected straight pipe 7, a sliding bearing extracted earlier is applied. It is possible that this will need to be squandered.
  • Then the sliding bearing 6 is gently crimped by a hammer in the groove 5. It is important not to damage the pressed bronze sleeve here.
  • Then the plastic tread 10 is cut in the place and tightly inserted into the pipe 7.
  • Next, the Deadwood shaft is connected to the steel rod, which will replace the flexible shaft 9. It is possible that this will need the help of a turner.
  • The final step. the rowing screw 3 is attached to the edible shaft 8 nut 2.

The collected bar is connected to the engine using specially manufactured adapters, the shape and size of which depend on the design features of a particular trimmer model for grass.

The benefits of alteration of the trimmer for grass in the boat motor

Engine power should be at least 0.7 kW. Ready.made nozzles for alteration (prefix for mounting to the engine, a special adjustable handle with a muffler button, fastening) can be purchased. After installing them on a trimmer for the grass, it remains only to connect the gas cable to the engine and connect the wires with the silencer.

Ready set of nozzles

Now they sell special nozzles for remaking a trimmer for grass in the boat motor. Such a prefix includes everything you need for fastening to the gasoline motor. The control handle and the switch button are mounted to the rod. The gas handle is made with the possibility of switching speeds and equipped with a rattle, which fixes the necessary position.

How to Cut Grass with String Trimmer

The kit includes a device for installing a device on a boat. The nozzle for a trimmer for grass can be collected easily, it has a simple design. For assembly, you should attach the gas cable to the motor, and then fix the muffler cable. The nozzle costs about 5 thousand in a specialized store. rubles.

How to make a boat motor with your own hands from a trimmer for grass?

To assemble a motor from a trimmer for grass to a boat, the manufacturer will need to prepare the following equipment and materials:

  • household lawn mower;
  • clamp. If it is not, then you can use any other mount for reliable fixation of the motor on the boat;
  • a sheet of duralumin, the thickness of which should not be less than 2 mm;
  • welding machine;
  • set of fasteners;
  • set of screwdrivers and wretched keys.

To assemble a home.made rowing screw, the manufacturer will need drawings. They should indicate the exact dimensions of the blades and the method of fixing them on the axis.

It must be remembered that the lower the power of the drive used and the mass of the boat, the less should there be a blades. For example, a screw with blades 10 × 3 cm is suitable for a boat with a mass of not more than 120 kg.

After the preparation of equipment and a thorough study of drawings, you can start assembling homemade.

The work algorithm should look as follows:

  • First of all, the manufacturer will need to finalize a bent shaft. First you need to dismantle the factory nut placed in a bobbin with a pre.wound fishing line. The nut itself in shape resembles a small 2-centimeter tube with internal thread. If necessary, it can be divided into 2 small full.fledged nuts. During the dismantling of fasteners, you need to be extremely careful so as not to lose them. If this happens, then finding another suitable fastener can no longer work;
  • After dismantling the nut, you will need to dismantle the plastic pad located on the gas button. There are no roller bearings at the end of the standard curved rod. They are replaced by an ordinary bronze sleeve, which is often called a sliding bearing. It needs to be gently extracted. Before this, you will need to unscrew the nut, as well as remove the daily and metal shafts from the tube;
  • Then you need to go to knocking out a plastic tread located on a flexible shaft. In the future, the steel pipe can be thrown away, since it will not be possible to align it with improvised means. It can be replaced by a duralumin pipe with the same diameter. It will need to install a bronze sleeve, which will need to be moved by a canvas using a hammer. Next, you need to take a plastic tread pre.trimmed in diameter, and install it on the pipe;
  • The next step will be the manufacture of the screw. To do this, you need to cut out duralumin blades and sharpen their edges. After that, each blade will need to bend up 1 cm up so that the screw step is at least 10 cm. You can fix the finished device using a nut;
  • Next, you need to install a bicycle speed switch on the boat motor from motorcycles, which will replace the standard plastic lining. After that, you will need to install a silencer that will take the engine exhaust away from the boat driver;
  • To fix the boat engine from the lawn mower, you need to use two plywood sheets. After that, the shaft will remain using 4 screws for this. During the transportation of a boat motor from a trimmer for grass, the shaft can be removed.

After the homemade nozzle is ready, it will need to run into. To do this, prepare a fuel mixture of fresh gasoline and motor oil in a ratio of 40: 1. After that, you will need to pour the finished mixture into a standard boat engine tank, start it, and let it develop 1 full fuel tank at idle. After running in, a home.made boat motor from a trimmer for grass will be completely ready to work.

Making mount and installation on the boat

To install a home.made motor on an inflatable boat, you will have to make a special mount. The following option is possible: the ring is used, to which the belt is attached. To connect the product with a transet, it is permissible to use an old unnecessary meat grinder. To do this, the lower part is cut in it, and a hole is drilled in the transverse plane with a diameter of 12 mm. This will also require a hairpin, with a diameter of 12 mm and a length of 100 mm. One side must be flattened and drilled a hole with a diameter of 6 mm. The m6 bolt is inserted into this hole, after which the eye of the braid braid is attached to this bolt using a nut.

The homemade device is installed on the boat in this order:

Despite this, a home.made boat motor is able to significantly make life a fisherman.
