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 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 crossing another boat's wake. Exces-
sive "bow-up" trim may result in the boat's bow
rising rapidly and possibly throwing the boat's oc-
cupants 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. 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 underway. Some boat, engine,
and propeller combinations may encounter boat
instability and/or high steering torque when oper-
ated 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 con-
ditions. If you experience boat instability and/or
high steering torque, see your Volvo Penta deal-
er to correct these conditions.
