MAINTENANCE
•Periodically,checkfluidlevelinHPU.Withtrimtabscompletelyretracted,fluid
level should be about 2" from bottom of reservoir (approximately 22 ounces). To
refill, remove lexan cover and filler plug located at the front left hand corner of the
reservoir. FILL WITH ANY TYPE AUTOMATIC TRANSMISSION FLUID (ATF) ONLY. Brands
or types of ATF can be mixed. Running HPU with an excess or lack of fluid will not
cause damage to the trim tab system.
•Periodically,checkforcleanelectricalconnectionsonbackofcontrol,HPUground
wire, and quick-disconnect plug.
•Coldtemperaturesdonotaffectthetrimtabsystem.Nowinterizationisnecessary.
•(SALTWATERONLY)Todeterelectrolysis,azincanodeshouldbeattachedtothetop
of each trim tab. Zinc must make direct contact with stainless steel. Do not paint
zinc. Do not ground trim tabs to other underwater appendages.
•Painttrimtabstodiscouragemarinegrowth.
1. Clean surface of all grease, oil, dirt.
2. Apply two coats of epoxy metal primer.
3. Apply two coats of anti-fouling paint.
Actuator, including the piston, may be painted.
•Unpaintedtrimtabsmayacquireanorangediscoloration.THISOXIDATIONOF
SURFACE CARBON MOLECULES IS NORMAL. The integrity of the stainless steel is not
affected. Orange coating can be cleaned off, but may eventually return. Note: This
discoloration should not be confused with the pitting and corrosion of electrolysis.
