Power Trim
The Power Trim system allows operator to raise and lower drive unit for trailering, beaching, launching and
shallow water operation. Power Trim also allows operator to adjust drive unit angle, while underway, to provide
ideal boat angle for varying load and water conditions.
1 In most cases, best overall performance is obtained with drive unit adjusted so boat will run at a 3° to 5° angle
to water.

2 Trimming Drive Unit UP/OUT Will:
• Lift bow of boat.
• Generally increase top speed.
• Increase clearance over submerged objects.
• Cause boat to accelerate and plane off slower.
• In excess, cause porpoising and/or propeller ventilation.
• Cause overheating if trimmed up/out beyond gimbal ring support flanges.
CAUTION
Never trim drive unit up/out using TRAILER switch while boat is underway. Severe damage to drive unit
may result if unit is raised beyond gimbal ring support flanges at engine speeds above 1200 rpm. For
shallow water operation, use extreme caution when operating boat with drive unit raised.

3 Trimming Drive Unit DOWN/IN Will:
• Help boat accelerate and plane off quicker.
• Generally improve ride in choppy water.
• In most cases, reduce boat speed.
• If in excess, lower the bow of some boats to a point at which they begin to plow with their bow in the water
while on plane. This can result in an unexpected turn in either direction called “bow steering” or “over steering”
if any turn is attempted, or if a significant wave is encountered.
