Operating in “bow-up” position
The “bow-up” position is normally used for cruising, running
with a choppy wave condition, or running at full speed. In a full
“bow-up” position the boat may tend to self-steer. You may
have to compensate with the steering wheel to keep the boat in
a straight-ahead path. In this position the boat’s bow will tend
to raise clear of the water. Excessive “bow-up” trim will cause
propeller ventilation resulting in propeller slippage. Engine
RPM will also increase, but boat speed will not increase and
may even drop.
CAUTION!
Use caution when operating in rough water or cross-
ing another boat’s wake. Excessive “bow-up” trim
may result in the boat’s bow rising rapidly and possi-
bly throwing the boat’s occupants into the water.
Operating in “bow-down” position
The “bow-down” position is normally used for acceleration onto
plane, operating at slow planing speeds, and running against a
choppy wave condition. In the fully “bow-down” position the
boat may tend to self-steer. You may have to compensate with
the steering wheel to keep the boat in a straight-ahead path. In
this position the boat’s bow will tend to go deeper into the wa-
ter. If the boat is operated at high speed and/or against high
waves, the bow of the boat will plow into the water. The boat
may tend to bow steer or spin about rapidly and possibly eject
occupants.
CAUTION!
The boat trim should be adjusted to provide balanced
steering as soon as possible each time you get un-
derway. Some boat/motor/propeller combinations
may encounter boat instability and/or high steering
torque when operated at or near the limits of the
“bow-up” or “bow-down” positions. Boat stability and
steering torque can also vary due to changing water
conditions. If you experience boat instability and/or
high steering torque, see your Volvo Penta dealer to
correct these conditions.
