energy of the water hitting the lower gear case, the propeller thrust
is directed by turning the stern drive, which can add to the steering
torque.
The prop tends to throw the stern to
port. Th
is is why experienced skippers
undertake a portside landing when wind
and current conditions permit. They
allow the prop to move the stern to port
toward the dock.
With a forward motion when the helm
wheel is turned hard to one side, the vessel
pivots around a point about 1/3 its length
abaft to stern. See illustration.
Stern drive boats have the ability to angle in or out their drive unit in
relationship to the transom. Th
is is accomplished by hydraulic shocks
located on the stern drive along with an electrical sender unit that
reads the drive angle and sends information to the dash trim gauge
showing a reading.
Purpose Of Power Trim
Th e purpose of the power trim/tilt is to enable the operator to change
the angle of the 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.
