gine accidentally starts when you are
near the propeller.

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 lanyard

the battery cut-off switch if your boat
has one.

peller when loosening or tightening the
propeller nut. Put a wood block be-
tween the anti-cavitation plate and the
