• 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.
2. Trimming out or up can:
• Lift the bow higher 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
• Cause engine overheating if any cooling water intake holes are above
the waterline
