Boat Systems Section 4
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 at the helm station, near the engine
controls. The system control box is located inside the
control console. There are also two electro-mechani-
cal actuator assemblies with stainless steel trim
planes fastened to the transom.
When the tab buttons are pressed, the trim tabs move
into position. Water force on the trim tab lower surface
creates upward pressure, raising the stern and lower-
ing the bow. Properly sized trim tab planes improve
boat performance over a wider range of loads,
weather, and water conditions.
The switch panel is labeled to make trim tab operation
simple. When operating the tab buttons, think of how
you want the bow of the boat to move to properly trim
the boat.
To lower the port bow, push the left DOWN button.
This lowers the trim plane on the starboard side of the
transom.
To lower the starboard bow, push the right DOWN
button. This lowers the trim plane on the port side of
the transom.
To evenly lower or raise the bow, you can push both
buttons at the same time. To evenly lower the bow,
push both DOWN buttons. To evenly raise the bow,
push both UP buttons.
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.
