If desired, you can make the outboard motor yourself from any trimmer. However, it is important to consider that the models are available with various accessories. Some trimmers use a long strut, and it will not be suitable for an outboard motor.
Problems also lie in finding a quality screw. It can be located in a horizontal or vertical position. In order to understand this issue in more detail, it is necessary to consider specific modifications.
Double Handwheel Devices
Converting the trimmer into a boat engine with a two-way flywheel is quite simple. The screw for this should be selected with a small diameter. The trimmer is suitable with manual adjustment and low power. Begin assembly by fixing the stand.
If we talk about a simple model, then the starter does not need to be touched. When assembling a deadwood, it is important to pay attention to fixing the connector. The screw is the last to be installed on the stand. The flywheel is attached to the starter in order to change the position of the pipe. Driving these motors is very simple. To prevent water from entering the connector, various covers are used.
Two-stroke models
You can make boat motors from a trimmer with a two-stroke engine with a short or long stand. An ordinary tube is suitable as a tiller. It is recommended to start the assembly by fixing the connector. At this stage, it is necessary to cut a special plate. In order to install it, some use metal corners. At the next stage, the starter is attached. In this case, the spring must not come into contact with the gear housing.
The trimmer adjuster must be protected from water. For some, the problem is with the fixation of the rack. So that she does not hang out, the tube is attached. It should be located in the upper part of the structure. In order to fix it, a welding machine will be required. At the last stage of assembly, a screw is attached to the stand.
Four-stroke engines
Going outboard motors from the trimmer is quite simple. Some people prefer not to use a power tool case. Specialists recommend taking the frame of another outboard motor for assembly. First of all, this will solve the problem of fixing the rack. It is also important to note that the model will be protected from water.
If we consider the classic version, then during assembly, a connector is taken and attached to the stator. Sometimes racks are used without fixing pipes. In this case, the tiller dimensions should be considered. Some experts use water pumps. In order to fix them, metal corners are installed above the deadwoods. The screws are mounted on a vertical delivery at the bottom of the rack.
Modifications on a manual starter
It is the easiest way to make outboard motors from a trimmer on a manual starter. The connector in this situation is fixed immediately after the tiller. Before starting the assembly, it is important to make a stand for sternwood. Next, select the screws for the motor. Many experts recommend choosing such elements of small diameter.
In order to fix the connector, it is more advisable to use metal corners. The control lever can always be made from a conventional pipe. At the last stage of assembly, the screw is checked, as well as the tiller. In this case, pay attention to the drive shaft. It should rotate freely, not hang out.
Protected Gearbox Model
With a protected gearbox, the outboard motor from the trimmer (drawings are shown below) is common. First of all, it is important to note that a tight casing is required for assembly. Before starting work, a rack is selected. You also need to pay attention to deadwood.
For a conventional trimmer, it is selected without pushers. In order to install the rack, protective plates are used. In the upper part of the structure, a support pipe is used. To tiller rotate freely, a small hole is made in the motor housing. Some experts still recommend soldering clamps. All this is necessary in order to easily install the motor on a boat.
Devices with anti-cavitation plate
Outboard trimmer motors with anti-cavitation plates are rare. However, if you have large racks, they can greatly help. First of all, such devices relieve the load from the support. It is also important to keep in mind that the deadwood on the motor wears out less. Some specialists use water pumps when assembling. If trimmers with low power are of interest, then they will not be required. Screws are used with a diameter of 15 cm. In some cases, the rack is fixed on a narrow platform.
Chainsaw Model
You can assemble a model from a chainsaw if there is a ready-made deadwood available. Also, the model will need a good stand. It is quite difficult to make it from a pipe yourself. Screws are used most often in small sizes. However, in this case, much depends on the power of the chainsaw. The clamp is fixed directly to the starter. In order to protect the device from water, a casing is used.
To fix the rack uses a long stem. Solder it should be in an upright position. Homemade outboard motors from a chainsaw with water pumps are rare today. It is also important to note that the clamp should be fixed together with metal corners. Some use screws or clamps for this.
Motor with regulator
Outboard trimmer motors with regulators are rare. To build the model you need a high-quality connector. The starter is most often used manual type. The lever for changing the position of the rack is used for a short length. Some install it to a clamp. Before mounting, it is important to clean the drive shaft carefully.
You should also pay attention to the lower rack to which the screws will be attached. Modifications with protected pushers are not considered in this case. Deadwood should be used without a camshaft. Before installing the flywheel, the connector and the starter are checked.
Model with reverse lock
Home-made boat motors are found only with a spring. The connector is used with a one-way flywheel. Some starter experts advise installing a manual type. To adjust the device, a regular tube is used. The clamp is used a small height. Two metal corners are suitable for its fastening.
An exhaust valve is mounted under the connector. Next, it is important to do the fixation. Some experts cut a non-metallic plate for this. It should be welded at the base of the crater. However, the drive shaft must rotate freely. To avoid cases of short circuit, a deadwood with a protection system is used.
Wide Pallet Devices
Homemade outboard motors with wide pallets are rare. This is due to the fact that the clamps for their assembly require very high. As a result, the model weighs a lot. Trimmers are usually selected with low power. For self-assembly of the motor, ordinary deadwoods are used. Connectors are installed with manual starters.
If the stand at the trimmer is very long, it should be shortened. A plate is welded at the end of the screw stand. Pushers in this case must be located at the base of the pallet. However, they should not be in contact with the clamp. In this case, the screws must be secured with a protective cover. Many experts also recommend using springs to reduce impeller wear.
