and remove the clip from the engine shut-
off switch. Turn off the battery cut-off
switch if your boat has one.
Do not use your hand to hold the propeller
when loosening or tightening the propeller
nut. Put a wood block between the anti-cavi-
tation plate and the propeller to prevent the
propeller from turning.
