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.
Trim Tab Adjustment
Propeller steering torque will cause your boat to pull in one direction. This steering torque is a normal thing that
results from your outboard not being trimmed so the propeller shaft is parallel to the water surface. The trim tab
can help compensate for this steering torque in many cases and can be adjusted within limits to reduce any
unequal steering effort.
