FEATURES AND CONTROLS
SHALLOW WATER OPERATION
When operating your boat in shallow water, the outboard can be tilted up to a
higher tilt angle. Reduce engine speed to idle for tilting. Operate the outboard
at slow speed while tilted up for shallow water operation. Keep the cooling
water intake holes submerged in the water and continue to check for water
discharge from the water pump indicator.

MANUAL TILT RELEASE
If the outboard cannot be tilted using the power 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.
Turn out the manual tilt release valve three turns counterclockwise. This allows
manual tilting of the outboard. Tilt the outboard to the desired position and
tighten the manual tilt release valve.

TILT-IN STOP ADJUSTMENT
NOTE: The outboard should be positioned against the tilt‑in stop pins during
operation.
