a - Too much angle (stern down - bow up)
b - Not enough angle (stern up - bow down)
c - Angle adjusted properly (bow slightly up)
Consider the following lists carefully when adjusting the operating angle of your outboard.
Adjusting the outboard close to the boat transom can:
• Lower the bow.
• Result in quicker planing off, especially with a heavy load or a stern heavy boat.
• Generally improve the ride in choppy water.
• Increase steering torque or pull to the right (with the normal right hand rotation propeller).
• In excess can lower the bow of some boats to a point where 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.
Adjusting the outboard away from the boat transom can:
• Lift the bow out of the water.
• Generally increase top speed.
• Increase clearance over submerged objects or a shallow bottom.
• Increase steering torque or pull to the left at a normal installation height (with the normal right hand rotation
propeller).
• In excess can cause boat porpoising (bouncing) or propeller ventilation.
Power Trim And Tilt (If Equipped)
Your outboard has a trim/tilt control called power trim. This enables the operator to easily adjust the position of the
outboard by pressing the trim switch. Moving the outboard in closer to the boat transom is called trimming in or
down. Moving the outboard further away from the boat transom is called trimming out or up. The term trim generally
refers to the adjustment of the outboard within the first 20° range of travel. This is the range used while operating
your boat on plane. The term tilt is generally used when referring to adjusting the outboard further up and out of
the water. With the engine turned off, the outboard can be tilted out of the water. At low idle speed, the outboard
can also be tilted up past the trim range to permit, for example, shallow water operation.
