TRIM TAB MAINTENANCE
Marine growth can interfere with the proper operation of the trim tab planes and actuators. To reduce
problems due to marine growth, always return the trim tabs to the full “UP” position after operating the boat
and periodically inspect and clean marine growth from the actuators and planes.
The trim tabs are equipped with a zinc anode to prevent galvanic corrosion. Galvanic corrosion is the corrosion
process occurring when different metals are submerged in an electrolyte. Sea water is an electrolyte and
submerged metal components must be properly protected. The anodes were installed at the factory and will
need to be changed when they are 75% of their original size.
Refer to the Routine Maintenance chapter of this manual for information on maintaining zinc anodes and the
trim tab owner’s manual for additional maintenance information, fluid specifications and operating
instructions.
