Trim Tab Zinc Plate

Each trim tab contains a sacrificial zinc plate (Figure 3-24) which prevents the development of corrosion
on the tab. This plate should be inspected and replaced when necessary.

Trim Tab Control Switches

There is a trim tab switch for each trim tab. The trim tab switches (Figure 3-25) are generally located on
the ignition control panel. When pressed, the switch activates the pressure pump that moves the trim tab in
the desired direction. Actual location of the switches may vary from model to model.
To correct for a listing condition you must lower the trim tab on the listed (lower) side by pushing the top
half of the rocker switch in a half second burst until the boat is righted.
If the stern of the boat is highly loaded, use both switches to operate both tabs, which lowers the bow when
the boat is on plane.
