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 in the bilge on the
transom. To service the unit, 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 create and push a hill of
water,increasing drag and requiring more power to
move through the water.

INSTRUCTIONS AND WARRANTY INFORMATION.
MANEUVERING/CONTROL HAZARD
Ensure continuous visibility of other boats, swimmers,
and obstacles during bow-up transition to planing.
