TRIM TABS
Electric/hydraulic trim tabs are standard equipment and
help provide maximum control of the hull in all water and
load conditions. If used properly, trim tabs can:
Always press the trim tab switches in short one
(1)
second bursts. If pressed too long, you can
overcompensate,andpotentiallylosecontrol. DO
NOT try to correct the situation by pressing the
other upper trim tab switch. Instead, raise the
tabslightlybypressingtheappropriatelowerhalf
of the trim tab switch.
a. Compensate for wind and load listing (level the boat
side to side).
b. Induce faster planing and help achieve optimum run-
ning angle (see Section E-6 - RunningAngle).
After stabilization of speed and direction, press the upper
half of the appropriate trim tab switch to achieve a level
side to side running attitude. Be sure to press the cor-
rect trim tab switch to obtain the desired result.
The proper use of electric/hydraulic trim tabs requires a
basicunderstandingof trimtaboperationandsomeprac-
tice in calm water. Be sure to read the manufacturer’s
literature included in the owner’s packet.
After pressing a trim tab switch, always wait and allow
time for the change in trim tab position to take effect. DO
NOT continue to press the trim tab switch while awaiting
trim tab reaction. By the time the effect is noted, the trim
tab will move too far and thus overcompensate.
The trim tab control uses two (2) momentary-type rocker
switches. The trim tab switches control the attitude or
position of the boat. The trim tab switches are labeled by
position such as “Bow Up” and “Bow Down”. They are
also labeled for “Port” and “Stbd”. When pressed, the
label indicates what happens to the bow of the boat.
Before leaving the dock and utilizing the trim tabs, ensure
the trim tabs are in the full up position. Press both lower
halvesofthetrimtabswitchesandhold(forapproximately
10
seconds) until the tabs are full up.
