CHAPTER 5
5-18
Single or twin outboard boats have the
ability to angle in or out their drive unit
in relationship to the transom. This is
accomplished by hydraulic shocks located
on the lower unit housing along with
an electrical sender unit that reads the
drive angle and sends information to the
chartplotter showing a reading.
The purpose of the power trim/tilt is to enable the operator to change
the angle of the outboard drive while at the helm. Changing the angle
of the drive or “trimming” provides the following benefi ts:
l. Improves acceleration onto a plane.
2. Maintains boat on plane at reduced throttle settings.
3. Increases fuel economy.
4. Provides smoother ride in choppy water.
5. Increases top speed.
