What is trim on a waverunner?

The trim system on a waverunner is a mechanism that adjusts the angle of the engine in relation to the hull of the waverunner. This adjustment changes the amount of drag on the hull, which can affect the speed, handling, and fuel efficiency of the waverunner.

There are two types of trim systems: manual and electronic. Manual trim systems require the rider to manually adjust the angle of the engine using a lever or knob. Electronic trim systems use a sensor to measure the speed and angle of the hull and automatically adjust the angle of the engine accordingly.

The trim setting on a waverunner should be adjusted depending on the conditions and the desired performance. In general, the trim should be set so that the waverunner is running level in the water. This will provide the best overall performance and handling. However, the trim may need to be adjusted if the waverunner is carrying a heavy load, if the water is rough, or if the rider is performing stunts.

For example, if the waverunner is carrying a heavy load, the trim should be set to a lower setting to reduce drag and increase speed. If the water is rough, the trim should be set to a higher setting to increase stability and reduce porpoising. If the rider is performing stunts, the trim may need to be adjusted to provide the best balance and control.

The trim system is an important part of a waverunner and should be used properly to ensure the best performance and safety.
