trim setting between the maximum “bow-up” and “bow-
down” positions.
The boat will be properly trimmed when the trim angle
provides the best boat performance for your operating
conditions. On models without power steering, the trim
position that provides a balanced steering load is desir-
able.
To familiarize yourself with the power trim, make test
runs at slower speeds and at various trim positions to
see the effect of trimming. Note the time it takes for the
boat to plane. Watch the tachometer and speedometer
readings and the ride action of the boat.
Operating in “Bow-up” Position
The “bow-up”
A
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 steer-
ing 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 crossing
another boat’s wake. Excessive “bow-up” trim may
result in the boat’s bow rising rapidly and possibly
throwing the boat’s occupants into the water.
Operating in “Bow-down” Position
The “bow-down”
B
position is normally used for accel-
eration 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
water. If the boat is operated at high speed and/or
against high waves, the bow of the boat will plow into
the water.
CAUTION!
The boat may tend to bow steer or spin about rapidly
and possibly eject occupants.
The boat trim should be adjusted to provide balanced
steering as soon as possible each time you get under-
way. Some boat, engine, and propeller combinations
may encounter boat instability and/or high steering tor-
que 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.
