MANEUVERING/CONTROL HAZARD
Ensure continuous visibility of other boats, swimmers,
and obstacles during bow-up transition to planing.
!
WARNING
The engine syncronization feature must be turned
OFF before docking or low speed maneuvering, this
allows full and separate control of each engine. Failure
to turn off the engine synchronization feature can
cause personal injury, damage to the vessel, and/or
the dock.

To trim the bow of your boat down, push the top
halves of BOTH rockers down in momentary bursts.
If you hold the rockers down, you will over trim the
boat and the bow will dig in. To correct over-trimming,
push bottom halves of BOTH rockers to obtain desired
planning angle.

RRANGEMENT
The two trim tabs on the transom of your boat can
also be used to trim the list of your boat (See chart
below) that may be caused by improper storage of
gear, too many people on one side or a strong cross
wind. Operation of the rocker switch should be
momentary bursts to achieve proper attitude of the
hull.
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 pumps are located on the aft bilge
bulkhead, mounted on the inside of 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 create and 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.

PROPERLY TRIMMED BOAT
•
Operates at a correct running attitude of a 3 to
5 degree angle to the water (bow slightly up).
•
Reduces drag and increases fuel efficiency.
•
Preserves good forward visibility.
•
Increases safety.
