To move a motor boat, a lightweight outboard motor is often installed. It is worth considering that such a mechanism is quite expensive and complicated to maintain.
Small boats are often equipped with motors trimmers. To date, they are very popular, to equip the purchase of a special nozzle. Consider its features in more detail.
What is a nozzle for remaking trimmer in boat engine?
Motors for light boats are often made from trimmers.
The main ones are the following:
- The clamp for installing a makeshift construction with a trimmer on the prepared boat transom was widely used. This option is considered more affordable, but it is characterized by increased efficiency in use. The special design allows the device to be used as a propeller. When performing the normal function of the motor, the mechanism is small, easy to install and remove, which determines a very wide distribution.
- Propeller screw. This embodiment is a little more complicated than the previous one, but there are already ready-made mechanisms on sale that are characterized by increased efficiency in use. It is not recommended to carry out the most powerful version, since due to the resulting traction, a light PVC boat can simply roll over. Often a special drive is included in the package of delivery, manufactured using corrosion-resistant steel, as well as some adapters that make the trimmer an almost universal outboard motor.
- Another common option is to remake a standard mower into a motor used to create traction. In this case, it is recommended to give preference to common trimmers, which require gasoline to work. The relatively light weight, which is 4.5 kg, is a significant advantage of this embodiment.
Principle of operation
When considering the trimmer, attention should be paid to the fact that such a mechanism provides a high speed of rotation of the blades. This ensures a high speed of movement of the boat on the water.

The features of the principle of work include the following points:
- The blades are turned out.
- The installed motor in the upper part transmits rotation to the blades.
- To increase reliability, the shaft that connects the engine to the blades is located in the protective tube.
Benefits of Using a Trimmer
The trimmer has a fairly large number of advantages that determine its distribution.
The main ones are the following:
- Relatively low cost.
- Simplicity of installation and dismantle.
- Light weight.
- High speed achieved when driving.
- High power, often excessive.
- Initially, there is a gas handle and a starter.
- There is a special leg that allows you to adjust the power of the device.
These and many other qualities determine the fairly widespread use of trimmers in recent years.
What are homemade boat engines made of?
If desired, the motor for a light boat can be made independently. In most cases, ready-made tools are used as a basis.
Often apply the following:
- The grass mower is ideal for creating a trimmer. It is intended for long-term operation, therefore it can last for a long period.
- In some cases, the construction mixer is reworked. In this case, batteries act as an energy source. This version is ideal for quiet fishing, but it is not designed for long-term use.
- A gasoline saw is rarely used. However, its design features determine that it is necessary to carry out a serious alteration.
How to make a boat motor with your own hands from a trimmer?
You can make a boat motor out of trimmer yourself.
This requires the following set of tools:
- Trimmer that acts as the basis for creating the future boat. For a small boat, it is recommended to create a structure with a power of 0.8 kW. Even this indicator is quite enough to achieve a speed of about 5-7 km / h. If the motor is created for a massive and heavy boat, then a more powerful trimmer should be selected.
- The screw in most cases is made of duralumin, the thickness of which is about 2 mm. Such a material can serve for a long period and does not form corrosion on the surface.
- To work with metal, a vice is also required that allows you to fix the material on its processing.
- A welding machine is required to connect the individual elements. It is best to use a semi-automatic version, since when using it, even if you do not have the proper experience, you can get a quality connection.
The manufacture of this product cannot be called a simple process, but it is still feasible at home.
The instruction is as follows:
- Prepare projects related to screw manufacturing. It is almost impossible to independently calculate.
- The edges of the screw are sharpened.
- The blades are often made curved by 10 mm. In some cases, the material is not bent, since it is characterized by a high degree of ductility.
- The screw locks into place on the trimmer head.
- On the Internet you can find a large number of adapters designed to connect the engine to the screw. They are cheap.
