Throttle Grip Friction Adjustment - Tiller Handle Models; Steering Friction Adjustment - Mercury 40 4-Stroke Manual

FEATURES & CONTROLS
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
