5. A good practice is to get underway with the outboard trimmed all the way in.
After the boat is on-plane, trim the outboard up slightly to obtain the proper
bow attitude and engine speed.
6. the outboard should never be trimmed up to a point where the propeller cavi-
tates (or slips). A rapid increase in engine rPM’s is evidence of cavitation. If
this occurs accidentally while running at full throttle, immediately trim the out-
board down and reduce the throttle until the slipping stops. If necessary, con-
sult your dealer for this problem.
If the prop slips at lower planing speeds, the outboard may be trimmed too far
up. Immediately trim the outboard down until the prop “grabs” again to restore
efficiency.
7. trimming the outboard up lifts the boat higher in the water. It will travel faster
because less hull is in the water.
STEERING FORCES
As the motor’s propeller turns, it causes a twisting force on the motor about its

Loss of Steering Control!
Improper trim adjustment can result in loss of steer-
ing and can cause a serious accident.
