Outboard motors from trimmer. Self-made outboard motors

If desired, the boat motor can be made from any trimmer. However, it is important to take into account that the models are manufactured with various accessories. Some trimmers use a long rack, and for a boat motor it will not be suitable.

Also, the problems lie in the search for a quality screw. It can be placed horizontally or vertically. In order to understand this issue in more detail, it is necessary to consider specific modifications.

Devices with two-way flywheel

Trimming the trimmer in 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 a manual regulator and low power. Begin the assembly with the fixation of the rack.

If we talk about a simple model, then the starter does not need to be touched. When assembling the deadwood it is important to pay attention to fixing the connector. The screw is installed on the rack in the last turn. The flywheel is attached to the starter to change the position of the pipe. Manage these motors is very simple. To prevent water from falling onto the connector, different housings are used.

Models with two-stroke engines

To make outboard motors from the trimmer with a two-stroke engine it is possible with a short or long rack. As a tiller, an ordinary tube is suitable. It is recommended to start the assembly with the fixation of the connector. At this stage, you need to cut out a special plate. For the purpose of its installation, some use metal corners. At the next stage, the starter is attached. In this case, the spring must not come in contact with the gear housing.

The trimmer controller must be protected against water ingress. Some people have a problem with fixing the rack. So that she does not hang, a tube is attached. It should be located at the top of the structure. To fix it, you need a welding machine. At the last stage of the assembly, a screw is attached to the rack.

Devices with four-stroke engines

Boat motors from the trimmer are assembled quite simply. Some people prefer not to use the power tool body. Specialists recommend for the assembly to take the skeleton of another boat engine. 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 classical version, then the assembly takes a connector and is attached to the stator. Sometimes the racks are used without fixing pipes. In this case it is necessary to take into account the dimensions of the tiller. Some experts use water pumps. For the purpose of fixing them over the sternware, metal corners are installed. Screws are attached to the vertical supply at the bottom of the rack.

Modifications on the manual starter

To make outboard motors from a trimmer on a manual starter is the easiest. Connector in this situation is fixed immediately behind the tiller. Before assembling, it is important to make a stern for deadwood. Next, you should choose the screws for the motor. Many experts recommend choosing such elements of small diameter.

For the purpose of fixing the connector, it is more appropriate to use metal corners. The control lever can always be made from a conventional pipe. At the last stage of the assembly, the screw is checked, as well as the tiller. In this case, it is necessary to pay attention to the drive shaft. It should rotate freely, do not hang out.

Model with protected gearbox

With a protected gearbox, the outboard motor from the trimmer (the drawings are shown below) is often found. First of all, it is important to note that a tight casing is required for assembly. Before starting work, the rack is selected. You also need to pay attention to deadwood.

For a normal trimmer, it is selected without pushers. Protective plates are used to install the rack. In the upper part of the structure a supporting pipe is used. In order for the tiller to rotate freely, a small hole is made in the motor housing. Some experts still recommend soldering clamps. All this is necessary in order to install the motor on the boat without problems.

Devices with anticavitacin plate

Boat motors from the trimmer with anti-cavitation plates are rare. However, in the presence of large racks, they can greatly help. First of all, such devices relieve the load from the support. It is also important to consider that the deadwood at the motor wears less. Some experts use water pumps when assembling. If trimmers with low power are of interest, they will not be required. The screws are used in 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 you have a ready-made deadwood. Also for the model you need a good rack. It is quite difficult to make it from a pipe independently. Screws are most often used in small size. However, in this case, much depends on the power of the chainsaw. Straight clamp is fixed behind the starter. In order to protect the device from water, a cover is used.

A long rod is used to fix the stand. Solder it in a vertical position. Homemade boat motors from chainsaws with water pumps are rare today. It is also important to note that the clamp should be fixed together with the metal corners. Some use screws or clamps for this.

Motor with regulator

Boat motors from the trimmer with regulators are infrequent. To build the model requires a quality connector. The starter is most often used manually. The lever for changing the position of the post is used for a short length. Some fix it to the clamp. The drive shaft must be carefully cleaned before fastening.

Also, attention should be paid to the lower rack, to which the screws will be attached. Modifications with protected pushers in this case are not considered. Deadwood should be used without a camshaft. Before installing the flywheel, check the connector, as well as the starter.

Model with a reverse lock

Self-made boat motors are found only with a spring. The connector is used with a one-way flywheel. Some specialist starter advise to install a manual type. A simple tube is used to adjust the device. The clamp is used for a small height. For its mounting, two metal corners are suitable.

An outlet valve is attached under the connector. Further it is important to do the fixative. Some experts cut a non-metallic plate for this. Weld it at the bottom of the crater. However, the drive shaft must rotate freely. To avoid short circuits, a deadwood with a protection system is used.

Devices with a wide pallet

Homemade boat motors with wide pallets are rare. This is due to the fact that the clamps for their assembly are very high. As a result, the model weighs a lot. Trimmers, as a rule, are selected with low power. For the self-assembly of the motor, conventional deadwoods are used. Connectors are installed with manual starters.

If the stand of the trimmer is very long, it should be shortened. A plate is welded to the end of the rack for the screw. The pushers in this case must be located at the bottom of the pallet. However, they must not come into contact with the clamp. In this case, the screws must be secured with a protective cover. Also, many experts recommend using springs to reduce the wear of the impeller.
