Operating in Bow-up Position
The bow-up position A is normally used for cruising,
running in a rough sea, or running at full speed.
WARNING!
Avoid excessive trim (bow-up) when crossing wakes
or rough seas, the boat's bow may rise or fall sharply,
possibly injuring the boat's passengers.
Be aware of these undesirable conditions that can
occur when running 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 on a straight path.
• The boat's bow will tend to raise clear of the water.
This reduces forward visibility from the helm.
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.
Operating in Bow-down Position
The bow-down position B is normally used for
acceleration onto plane, operating at slow planing
speeds, and running against a rough sea.
WARNING!
Avoid excessive trim-in (bow-down) when operating at
speed and/or in rough seas. The boat's bow may dive
in to oncoming waves, causing the boat to bow steer
or spin rapidly, possibly injuring the boat's passengers.
Be aware of these undesirable conditions that can
occur when running In a full bow-down position;
• The boat may tend to self-steer. You may have to
compensate with the steering wheel to keep the
boat on a straight path.
• The boat's bow will tend to go deeper into the water,
reducing ride quality.

Trim/Tilt Motor Protection

The trim/tilt motor is protected from overheating by an
internal thermal overload switch. If the trim switch is
held too long at either full up or full down, the electric
motor may stop. If the motor stops, release the trim
switch and wait for 20 seconds. Then try the switch
again.
