If your boat is equipped with an electrical engine trim, you should familiarise yourself with its use in order to obtain all the benefits offered by the device. Trim can have a major impact on the boat’s handling and fuel economy. By trimming the engine out when driving, you can reduce water resistance until you reach the optimal running speed. To prevent the engine from cavitating and racing, you should trim the engine in a little and reduce revolutions and speed before turning.

Rising to plane

The boat will rise to plane best if you keep the engine completely trimmed in. As your speed increases, you should trim the engine to reduce resistance. The best way to discover the best cruising speed for your boat is experimentation. When you reduce speed or encounter rough seas, you can trim the engine back in to lower the bow and prevent the waves from pummelling the bottom of the boat. As an exception to this general rule, you can be instructed to trim the engine out in following seas, as this will lift the boat’s bow and prevent it from cutting the waves too easily.
