the propeller. Before inspecting, remov-
ing, or installing the propeller, place the

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.

sion from cavitation or ventilation, or other
damage.
Check the propeller shaft for damage.
Check the splines for wear or damage.
