• Lift the bow higher out of the water.
• Generally increase top speed.
• Increase clearance over submerged objects or a shallow bottom.

height (with the normal right‑hand rotation propeller).

ventilation.
• Cause engine overheating if any cooling water intake holes are above
the waterline.
TILTING OPERATION
To tilt the outboard, shut off the engine and press the trim/tilt switch or auxiliary
tilt switch to the up position. The outboard will tilt up until the switch is released
or it reaches its maximum tilt position.
1. Engage the tilt support lever by rotating the knob to bring the support
lever upward.
2. Lower the outboard to rest on the tilt support lever.
3. Disengage the tilt support lever by raising the outboard off the support
lever and rotating the lever down. Lower the outboard.
MANUAL TILTING
If the outboard cannot be tilted using the power trim/tilt switch, the outboard can
be manually tilted.
NOTE: The manual tilt release valve must be tightened before operating the
outboard to prevent the outboard from tilting up during reverse operation.
