Warning System - Mercury 10 EFI FourStroke Installation, Operation & Maintenance Manual

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 oversteering) 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
