WARNING
 Stop the engine before adjusting the
trim angle.
 Use care to avoid being pinched when
removing or installing the rod.
 Use caution when trying a trim position
for the first time. Increase speed gradu-
ally and watch for any signs of instability
or control problems. Improper trim an-

TIP:
The outboard motor trim angle can be
changed approximately 4 degrees by shifting
the trim rod one hole.

Adjusting boat trim

When the boat is on plane, a bow-up attitude
results in less drag, greater stability and effi-
ciency. This is generally when the keel line of
the boat is up about 3 to 5 degrees. With the
bow up, the boat may have a greater tenden-
cy to steer to one side or the other. Compen-
sate for this as you steer. When the bow of
the boat is down, it is easier to accelerate
from a standing start onto plane.
