How to Increase the Horsepower of an Outboard Motor?

Perfect House Blog

Do you want to know how to increase the horsepower of an outboard motor? If so, you’ve come to the right place. This article will show you how to make your outboard motor more robust.

Choose the Right Motor:

Are you aware that for increasing the horsepower and speed of an outboard motor, choosing the best motor is equally essential? We’ve highlighted some important points you must consider while selecting a suitable motor.

Several factors are essential while selecting a motor, but voltage, current, torque, and velocity are the most vital.

  •  Electric Current is the factor that starts the motor, and applying too much current can damage it too. 
  • Voltage: The higher the voltage, the higher the motor’s torque. Voltage helps net current flow in a direction.
  • Torque: The torque the motor produces when power gets transferred to the motor determines the operating torque and motor speed. It is a more critical factor than the speed of the motor.
  • Velocity: The RPM of the motor can be different and complex. The gearing system doesn’t always make the motor run at the highest speed.

Check the Tolerance

In any energy conversion, motor tolerance and efficiency plays a significant role. For horsepower rating, there is efficiency and tolerance associated with the motor. So, one must check and calculate the tolerance for a more energy-efficient motor.

For motors rated to less than 150kw, the tolerance should be -15%of, subtracting the decimal value of efficiency from the number 1.

Replace the Spark Plugs

The spark plugs get damaged when the engine operates at excess heat or misfires. Do we face issues like the engine’s voice is rough and has become noisy? The acceleration often becomes slow, or the spark plugs need a replacement immediately if the motor is hard to start. Spark plugs are usually designed for the long run and need replacement after 80,000 to 100,000 miles.

Use Clean Fuel 

A motor needs proper fueling and servicing for it to operate efficiently.

Fuel will ensure that the ignition and compression are running smoothly and help maintain the motor.

Check the Air Filter

Engine horsepower gets affected due to dirt and dust. Air filters need proper cleaning and maintenance to keep them running and stable.

If the air filter looks dirty, replace it immediately. You should also replace the filter if you observe black smoke leaving the pipe, or if there is a smell when the engine starts.

Engines Need Coolant Always

Have you ever stopped in the middle of a journey because your outboard engine overheated or seized up? Then coolant is used as a source to pull away all the heat from the engine.

Overheating and continuous use of these engines can damage the engines permanently. The performance of an outboard motor can be efficient and faster when performed at optimum temperatures. 

Keep the Propeller in Good Condition

Propeller works by turning the torque into the thrust of an outboard motor. Simply put, it takes power from the engine and converts it into action. This action creates a type of force behind the blades. So, the propeller must be kept in a reasonable and appropriate condition to keep the outboard motor efficient.

The blades should be in clean condition and mind the gravel. Conduct comprehensive inspections of blades and also keep up with regular oil changes of a Propeller.

Follow these simple steps, and you will be able to increase the horsepower of your outboard motor. Perfect House helps you by guiding the proper usage of your outboard through practical steps and tips. For more blogs on the efficient operation of outboards, check out our blog section.
