Furthermore, added to the energy of the water hitting the lower gear
case, the propeller thrust is directed by turning the stern drive, which

TRIM ANGLE

Stern drive 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 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
The 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.

can add to the steering torque.
The prop tends to throw the stern to port.
This 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.
