EMU29171
Checking propeller
WARNING
EWM00321
You could be seriously injured if the en-
gine accidentally starts when you are near
the propeller.
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 remove the key,
and remove the lanyard from the engine
stop switch. Turn off the battery cut-off
switch if your boat has one.
Do not use your hand to hold the propel-
ler when loosening or tightening the
propeller nut. Put a wood block between
the anti-cavitation plate and the propel-
ler to prevent the propeller from turning.
Checkpoints
Check each of the propeller blades for
wear, erosion from cavitation or ventilation,
or other damage.
Check the propeller shaft for damage.
Check the splines / shear pin for wear or
damage.
Check for fish line tangled around the pro-
peller shaft.
Check the propeller shaft oil seal for dam-
age.
NOTE:
If the shear pin equipped: it is designed to
break if the propeller hits a hard underwater
obstacle to help protect the propeller and
drive mechanism. The propeller will then spin
freely on the shaft. If this happens, the shear
pin must be replaced.
