Boat Systems
The trim tab control box senses switched 12 VDC at
the starboard engine key switch.
• The trim tab system will only operate when the
starboard engine key switch is ON
• The trim tabs will automatically retract when the
starboard engine is turned OFF
When the trim planes are lowered, the LED displays
will indicate the position of the planes by lighting more
LED segments. As the switch is pressed to the up
position, the LED segments will go out.
Proper Boat Trim
All boats “break over” or get on plane at a particular
speed. This speed is determined by load distribution,
water conditions, and other factors. Trim tabs allow
your boat to plane at speeds below the natural planing
speed. By pressing the control to the BOW DOWN
position, your trim tabs move down. This will raise
your stern and lower your bow, getting the boat on
plane sooner.
When learning to use trim tabs, begin by pressing the
control switches in ½ second bursts for gradual trim-
ming. A momentary delay occurs from the time you
move the control switch to the time the boat reacts.
This is normal and varies with boat speed. Be careful
not to over-trim the boat. An over-trimmed boat will
“plow” or “bow-steer”. If you over-trim the boat, push
both trim switches back to the BOW UP position to
raise the bow.
!
CAUTION
The trim tabs will automatically retract when the
starboard engine is turned OFF. Make sure that
both trim tabs are fully retracted before you put
the boat on a trailer, cradle, or boatlift. Contact
with the trim tabs can cause serious damage to
the tabs and the boat.
