Adjusting Boat Trim - Yamaha VF200 Owner's Manual

Operation
Use caution when trying a trim angle for

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 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 angle with this switch while the
boat is moving.
Adjust the outboard motor trim angle using
the power trim and tilt switch.

Make test runs with the outboard motor set at
different trim angles to find the position that
works best for your boat and operating con-
ditions.

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 per-
formance further, and the boat may "por-
poise" (hop in the water), which could throw
the operator and passengers overboard.
