Boat Trim Tabs
Your boat is equipped with Lenco
®
electro-mechanical
trim tabs. The trim tab control buttons and LED indica-
tor lights are located on the control console face, near
the engine controls.
Using the boat trim tabs properly requires experience
and skill. Always operate any boat system within the
limits of your experience. If you do not have this expe-
rience, ask someone to instruct you or gain experience
through experimentation under controlled conditions.
You can use the boat trim tabs to:
• Adjust for uneven load distribution
• Adjust for strong crosswinds
• Adjust for changing weather conditions
• Trim the boat fore and aft
• Trim the boat port and starboard
• Improve ride smoothness
• Improve boat performance
The electro-mechanical cylinders and trim tabs are
located on the lower portion of the boat’s transom.
The trim tab control box senses switched 12 VDC at
the outboard engine main ignition key switch.
• The trim tab system will only operate when the
outboard engine main ignition key switch is ON
• The trim tabs will automatically retract when the
outboard engine main ignition key switch is turned
OFF
!
WARNING
The boat’s attitude and steering effort can react
very quickly to changes in trim tab position.
Adjust trim tab deployment in small increments
to avoid loss of boat control.
