TRIMMING OUTBOARD
MOTOR
The trim angle of the outboard motor helps
determine the position of the bow of the
boat in the water. The correct trim angle will
help improve performance and fuel econo-
my while reducing strain on the engine. The
correct trim angle depends upon the combi-
nation of boat, engine, and propeller.
Correct trim is also affected by variables
such as the load in the boat, sea conditions,
and running speed.
w
Excessive trim for the operating condi-
tions (either trim up or trim down) can
cause boat instability and can make
steering the boat more difficult. This
increases the possibility of an accident.
If the boat begins to feel unstable or is
hard to steer, slow down and/or readjust
the trim angle.
NOTE:
Refer to the section “ADJUSTING TRIM
ANGLE” for instructions on usage.
