• Operates at a correct running attitude of a 3 to 5
degree angle to the water (bow slightly up).
• Reduces drag and increases fuel efficiency
• Preserves good forward visibility.
• Increases safety.
Use short bursts of trim tab switches to adjust trim
tabs. Holding switches too long at once may cause
sudden steering problems. Adjusting one trim tab
more than the other will adjust list caused by
improper equipment storage, too many people on
one side or a strong cross wind.

AUGE
The power trim allows the operator to raise and
lower the stern drive unit while underway to provide
the ideal boat angle (in relation to water surface) for
a given load and water condition (Fig. 2.12.2).
Trimming UP rotates the stern drive and propeller
away from the transom. Trimming DOWN rotates
the stern drive and propeller closer to the transom.
When the stern drive is trimmed DOWN, the bow
of the boat is being forced down. If the trim is in the
full DOWN position when accelerating from idle to
plane, the boat will plane faster with less bow rise.
Once on plane, the stern drive unit can be trimmed
UP slightly. This will raise the bow of the boat slightly
and increase speed. You will need to try small
differences in the stern drive position to determine
the trim position you prefer under various conditions.
