Before inspecting, removing, or install-
ing the propeller, remove the spark
plug caps from the spark plugs. Also,
place the shift control in neutral, turn
the main switch to “
” (off) and re-
move the key, and remove the cord
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 pro-
peller when loosening or tightening the
propeller nut. Put a wood block be-
tween the anti-cavitation plate and the
