You could be seriously injured if the en-
gine accidentally starts when you are near
the propeller. Before inspecting, remov-
ing, or installing the propeller, move the
remote control lever to the neutral posi-
tion, turn the main switch to the “ ” (off)
position, remove the key, 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. Place a block of wood between the anti-
cavitation plate and the propeller to prevent
the propeller from turning.
Checkpoints
Check each of the propeller blades for ero-
sion from cavitation or ventilation, and oth-
er damage.
Check the propeller shaft for damage.
Check the splines for wear and damage.
Check for fish line tangled around the pro-
peller shaft.
