Mercury 75 Operation Maintenance Warranty Installation Manual page 66

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.
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 the engine speed below 2000 RPM.
2. Tilt the outboard up. Make sure all the water intake holes stay submerged
at all times.
3. Operate the engine at slow speed only. If engine speed exceeds 2000
RPM, the outboard will automatically return down to the maximum trim
range.
AUXILIARY TILT SWITCH
The auxiliary tilt switch can be used to tilt the outboard up or down using the
power trim system.
