tion onto plane and the best towing power for skiing.
The bow-down position is normally used for accel-
erating from a standing start or from idle speed.
Operating Conditions:
In the bow-up position, your boat may tend to pull to
the left. If this condition exists, correct it by applying
a clockwise force with the steering wheel to keep on
a straight path. The trim tab can also be adjusted to
compensate for steering wheel torque, but adjust
the trim tab only if bow-up is commonly used. Refer
to Trim Tab.
Operating Conditions:
In the bow-down position, your boat may tend to
pull to the right. If this condition exists, correct it by
applying a counterclockwise force with the steering
wheel to keep on a straight path. The trim tab can
also be adjusted to compensate for this steering
wheel torque, but adjust the trim tab only if bow-
down is commonly used. Refer to Trim Tab.
When the motor is trimmed to full bow-up position,
the boat’s bow will tend to rise above the water.
When the motor is trimmed to full bow-down posi-
tion, the boat’s bow will tend to go deeper into the
water (plow).
Excessive bow-up trim may cause propeller ventila-
tion, resulting in propeller slippage.
WARNING
IMPORTANT: Some boats plow, or are difficult to
plane, when operated in the trim’s lowest position.
If your boat handles unsuitably when trimmed fully
bow-down, set the angle adjusting rod or trim limiter
rod to limit the travel of the power trim. If your motor
is not equipped with this rod, purchase one from
your Dealer.
When operating in rough water or crossing
a wake, excessive bow-up trim may result in
the boat’s bow suddenly rising skyward,
possibly ejecting occupants.
WARNING
WARNING
If the bow of the boat plows the water at
high speeds, the boat may bow steer or spin
suddenly, possibly ejecting occupants.
Some boat/motor/propeller combinations
may encounter boat instability and/or high
steering torque when operated at high
speed at or near the motor’s trim range lim-
its (full bow-up or bow-down). Boat stability
and steering torque can also vary due to
changing water conditions. If any adverse
conditions occur, reduce throttle and/or
adjust trim angle to maintain control. If you
experience boat instability and/or high
steering torque, see your Dealer to correct
these conditions.
