ECTION
When running wide open, most boats do not require
any trim unless heavily loaded.
In heavy following seas or when running in an inlet,
best maneuverability is obtained with a bow high
attitude. To be sure the tabs are full up in the zero

position, push the bottom halves of BOTH rockers
for several seconds.
The trim tab pump is located starboard, on the
transom. To service the units, remove the tinted
plastic cover to gain access to reservoir fill plug
and motor parts. Hydraulic trim tabs use Type A
Dexron II automatic transmission fluid, which should
be filled up to the FULL mark on the pump base.
Add fluid with the trim tabs in the up position
only.
Your boat is designed to plane at a particular speed
and weight distribution. As speed decreases or
weight increases, the stern will settle lower in the
water and the hull will push a hill of water, increasing
drag and requiring more power to move through the
water.
Hydraulic trim tabs are adjusted independently of each
other, enabling adjustment of bow attitude up and down
as well as to correct for side to side list. Trim tabs
also provide attitude adjustment at lower speeds.

Increases safety.
Use short bursts of rocker switches to adjust trim tabs.
Pushing switches too far at once may cause sudden
steering problems. Adjusting one trim tab mare than
the other will adjust list caused by improper equipment
storage, too many people on one side or a strong cross
wind.
