Adjusting trim angle

WARNING
Make sure that all people are clear of the
G
outboard motor when adjusting the trim
angle. Body parts can be crushed be-
tween the outboard motor and the clamp
bracket when the outboard motor is
trimmed or tilted.
Use caution when trying a trim angle for
G
the first time. Increase speed gradually
and watch for any signs of instability or
control problems. Improper trim angle
can cause loss of control.
If the outboard motor is equipped with a
G
power trim and tilt switch located on the
bottom cowling, use the switch only
when the boat is at a complete stop with
the engine off. Do not adjust the trim an-
gle with this switch while the boat is
moving.
Adjust the outboard motor trim angle using
the power trim and tilt switch.

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.
Bow Up
Too much trim-out puts the bow of the boat
too high in the water. Performance and econ-
omy are decreased because the hull of the
boat is pushing the water and there is more air
drag. Excessive trim-out can also cause the
propeller to ventilate, which reduces perfor-
mance further, and the boat may "porpoise"
(hop in the water), which could throw the op-
ZMU06981
erator and passengers overboard.
