POWER TRIM OPERATION
The power trim and tilt feature of the outboard is convenient for drifting and when operating at low throttle speed
in very shallow water. When under power, do not trim out the outboard in an effort to gain speed as is done with
a conventional propeller driven boat.
When planing, the outboard should be positioned vertical or tilted in toward the boat to provide a scooping angle
on the water intake grate. Tilting the outboard out beyond a vertical position reduces the scoop angle and can
cause impeller slippage and cavitation burns on the impeller blades.
TILTING OPERATION
To tilt 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 knob to bring the support lever upward.
2. Lower 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.
1. Turn out the manual tilt release valve 3 turns (counterclockwise). This allows manual tilting of the outboard.
NOTE: The manual tilt release valve must be tightened before operating the outboard to prevent the outboard from
tilting up during reverse operation.
2. Tilt the outboard to the desired position and tighten the manual tilt release valve.
AUXILIARY TILT SWITCH
The auxiliary tilt switch can be used to tilt the outboard up or down using the power trim system.
