Engine (Power) Trim
Each engine uses a trim switch
performs the following functions:
• Moves the sterndrives angle up or down to provide optimum running conditions.
• Allows the boat to come up on plane more quickly and efficiently.
• The power trim also allows the sterndrives to be fully raised so that the boat may be trailered or
un-trailered without damaging the sterndrive/propeller.
When using the engine trim, keep the following in mind:
• Avoid a bow-down condition. This is known as "plowing" which can result in unintentional
consequences. Readjust trim to correct this condition.
• Avoid a bow-up condition. This is known as "porpoising" or "propeller ventilation." This
condition creates an unsafe propeller speed which may damage the engines. Reduce engine RPM
and readjust trim to correct this situation.
• When attempting to come up on plane always start with the sterndrives down.
