Trim Tabs
Your boat is equipped with Lenco
®
electro-mechanical
trim tabs. The trim tab system consists of four major
components. The switch panel with LED tab indica-
tors is located on the control console. The system
control box is located inside the control console.
There are also two electro-mechanical actuator
assemblies with stainless steel trim planes fastened to
the transom.
When the switches are pressed, the trim tabs move
into position. Water force on the trim tab surface cre-
ates upward pressure, raising the stern and lowering
the bow. Properly sized trim tab planes improve the
performance of your boat over wider load range,
weather, and water conditions.
The switch panel is labeled to make tab operation sim-
ple. When operating the trim switches, think of how
you want the bow of the boat to move to properly trim
the boat.
To lower the port side of the bow, push the left switch
forward. This lowers the trim plane on the starboard
side of the transom.
To lower the starboard side of the bow, push the right
switch forward. This lowers the trim plane on the port
side of the transom.
To evenly lower or raise the bow, you can push both
switches in the same direction at the same time. To
evenly lower the bow, push both switches forward .
To evenly raise the bow, push both switches back .
The Lenco switch panel includes two LED segment
bars that represent the relative position of both trim
tabs. When you lower one or both of the trim tabs, the
LED segment bars will extend to indicate that the trim
tabs are moving down. When you raise one or both of
the trim tabs, the LED segment bars will retract to indi-
cate that the trim tabs are moving up.
