FEATURES AND CONTROLS
Operating the boat at high speeds with the outboard trimmed too far under
can create excessive bow steer, resulting in the operator losing control of
the boat. Install the trim limit pin in a position that prevents excessive trim
under and operate the boat in a safe manner.
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.
• In excess, can cause boat porpoising (bouncing) or propeller
ventilation.
• Cause engine overheating if any cooling water intake holes are above
the waterline.
