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 tab fluid should be checked often. Keep the fluid level between the marks on the trim
tab pump reservoir.
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 specifi-
cations and operating instructions.
