AUXILIARY TILT SWITCH
The auxiliary tilt switch can be used to tilt the outboard up or
down using the power trim system.
SHALLOW WATER OPERATION
When operating your boat in shallow water, you can tilt the
outboard beyond the maximum trim range to prevent hitting
bottom.
1. Reduce engine speed below 2000 RPM.
2. Tilt outboard up. Make sure all the water intake holes stay
submerged at all times.
3. Operate the engine at slow speed only.
