C.Trailer Switch
The trailer switch (Power Tilt) is not to be confused with the Power Trim function. The trailer switch is to be used only when the engine is off.
The trailer switch allows the drive unit to be raised for trailering, beaching and launching. To operate, press and hold the trailer switch until the drive unit reaches the end of upward travel. The mechanism that raises the lower unit will stop operating at the end of the upward travel. To bring the drive unit down into boating position, push the power trim switch down.
D.Trim Tabs
The trim tabs (see Figure 2.6.1) are different from the stern drive unit trim control. The trim tabs are two flat plates, hinged below the water line on the transom at the rear and are raised and lowered hydraulically by using the rocker switches located at the helm station.
The trim tabs are used to adjust the sideways listing of the boat due to uneven loading, a strong cross wind or propeller torque. The twisting effect of propeller torque is especially pronounced when running the engine at high horsepower output.
To correct the listing, adjust the trim tabs to level the boat. When the boat is level, right to left, the steering effort will be the same for right and left turns.
Lower the trim tab on the listing (lower) side by pushing the top half of the rocker switch in
Using both switches to lower both tabs on a side-
When running at cruising speed, the trim tabs should be fully up, unless the rear is heavily loaded.
In heavy following seas or when running in an inlet, best maneuverability is obtained with a bow high attitude. To be sure the tabs are full up, push the bottom halves of the rockers for several seconds.
