Trim Tab Control Box
The trim tab control box operates on power supplied
through the accessory fuse block. The trim tab power
circuit is protected by a 20-amp blade fuse. The trim
tab control box senses 12 VDC when the outboard
engine ignition key switch is in the ON position.
Because the trim tab control box senses switched
12 VDC at the outboard engine ignition switch:
• The trim tab system will only operate when the
outboard engine ignition switch is
ON
• The trim tabs will automatically retract when the
outboard engine ignition switch is turned
OFF
Turning the house battery OFF-ON switch to the
OFF
position at the end of your mission will cut power to the
trim tab control box.
!
CAUTION
The trim tabs will automatically retract when the
outboard 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.
