How to increase the power of the boat motor? Boat motors, characteristics, fuel

When buying a boat engine, most inexperienced boat owners stop picking the least powerful units. The reason for all is the affordable cost of such engines. However, after a while shipowners find themselves unhappy with the acquisition due to restrictions in the speed of movement. Let's find out how to increase the power of the boat motor? What measures can be taken to noticeably "disperse" the engine of the motor boat?

How to really improve the performance of boat motors?

Increase the number of horsepower in low-power engines is quite possible. In particular, it concerns imported boat motors.

As practice shows, buying a relatively inexpensive boat engine of an authoritative brand, you can work on its refinement, which will make it possible to obtain a model with characteristics similar to those from the upper price category. The most popular solutions include the following:

1. Comparison of technical parameters of the existing unit with the top model, to which the ship owner aspires. Increase in power in this case helps to replace the exhaust manifold, petal valves, carburetor.
2. Removing the power limiter. To increase the parameter, in addition, it is possible to refine the nodes, which control the fuel consumption of boat engines, in particular, they are responsible for supplying fuel to the combustion chamber.
3. Boring the carburetor. The operation is aimed at increasing the diameter of the diffuser and, as a result, affects the increase in the power of the engine.
4. Call for advice to the mechanics of the service center. The specialists will not only prompt how to increase the power of the boat engine of a particular brand, but also pick up suitable parts, the installation of which will increase the amount of horsepower.

How to increase the power factor without modifying the engine?

To increase the amount of horsepower, sometimes you should simply improve the condition of the underwater part of the boat. Any formations that are concentrated on the bottom surface must be cleaned in a timely manner.

Do not bypass the busyness of the interior of the ship and the cockpit. How to increase the power of the boat motor? For this it is recommended to remove all unnecessary things on the shore, which affect the overall weight of the boat. Leave only the most necessary equipment on board.

It is not necessary to save too much by pouring oil into the gasoline for the boat engine. Using a low-quality fuel mixture will only cut the number of horses.

One of the defining omissions on the part of the shipowner is the presence of chips on the engine blades. As practice shows, this leads to the fact that the fuel mixture is consumed in much larger volumes when the desired speed is reached.

Additionally, the pressure level in the cylinders should be assessed. The latter must be pumped with air until the appearance of a characteristic ringing. The need for the maximum filling of cylinders is due to a decrease in pressure when they cool down in water. Strangely enough, this factor may also affect the deterioration of the performance of the boat.

Increase the power of two-stroke boat engines

To increase power, it is worth carefully selecting the oil for two-stroke boat motors. Preference should be given to the production of proven, proven brands. Choosing an expensive oil for two-stroke boat motors, you can get a gain in power by several horsepower.

In order to increase the parameter, it is recommended to work on the carburetor. After disassembling the structural element, it is necessary to increase the diameter of the diffuser, to correct the work of the float dispenser of the fuel.

Increase the power of two-stroke boat motors contribute to the adjustment of the angle of ignition. Here it is worth making the settings aimed at easy advance. Hence the need for the installation of new spark plugs.

Increase of power of four-cycle boat motors

It is somewhat more difficult to complete the four-stroke engines. To increase the power indicators, it is necessary to adjust the gaps of the dampers of the gas distribution mechanism. In particular, the expansion of the latter makes it possible to substantially increase the flow of the fuel mixture.

If we talk about the most productive four-cycle boat motors, to increase their power will have to reflash the electronic unit. This solution allows you to remove a whole lot of restrictions provided by the manufacturer. It is extremely difficult to cope with such work independently. Therefore, it is better for inexperienced shipowners to immediately seek help from an appropriate service.

Outboard motor Salyut

According to the feedback of the experienced ship owners, the engines of the Salyut brand are one of the most problematic outboard motors. However, despite this circumstance, the owners of the boats continue to trust such units because of their low cost, as well as wide availability of parts.

One of the main reasons according to which the Salyut boat engine loses power is the concentration of water in the carburetor. You can get into trouble even while driving through calm water in calm weather. The spray sucks into the motor element, and the latter begins to stall. Eliminate the problem and, accordingly, increase the power of this engine makes it possible to install a special nozzle on the diffuser, which will provide air to the carburetor through the "nose", which is directed away from the direction of motion of the boat.

In motors of the Salyut brand, the quality of the crankshaft manufacturing material is also desired. The use of insufficiently reliable steel by the manufacturer leads to rapid depletion and failure of the specified part. How to increase the power of the boat motor? Elimination of the factor that affects the loss of horsepower, here can serve as the installation on the crankshaft of an additional sleeve made of brass. This solution will protect the functional element of the engine from corrosion and eliminate the ingress of water into the gas receiver.

Yamaha Motor

In such engines, even the replacement of the carburetor for more advanced options solves a little. For improvement here it is recommended to remove the factory power limiter, and also to bend the valve petals in the throttle valve.

It should be noted that on Yamaha engines, the installation of limiters is performed from environmental motives. In many Western countries, strict laws apply to the amount of harmful emissions to the atmosphere. Therefore, the manufacturer simply has to resort to such a decision.

Suzuki engine

To increase the power in the motors of the presented brand, it is necessary to resort to cleaning the carburettor and the collector, and also to replace the gaskets between these structural elements. The refinement procedure here is as follows:

• Neatly dismantled hoses and tubes, which can interfere with the work;
• Removes the fastener that holds the carburetor;
• New gaskets are located in the right places;
• After dismantling the thermostat, the cooling system is cleaned;
• The components are assembled in the reverse order.

Honda Motor

Boat engines of this brand have long established themselves as the most productive units. However, even here there is room for increasing the amount of horsepower. The following solutions help to increase the power of Honda engines:

• Timely, systematic maintenance;
• The content of the engine air filter in perfect condition;
• Installation of a reliable device that is capable of providing the most efficient air passage;
• The use of quality additives for fuel (allows you to save fuel consumption of boat engines).

Finally

Absolutely every engine of the boat engine can be improved in order to increase the power indicators. However, not all motors are amenable to forcing with ease. Sometimes such events look too expensive. Therefore, in order to avoid the loss of time and energy, in some cases it is worth initially to be guided by the purchase of the unit with the desired capacity.
