CHECKING PROPELLER; SHEAR PIN
AND COTTER PIN
w
You could be seriously injured if the
engine accidentally starts while you are
near the propeller.
8 Before inspecting, removing or
installing the propeller, remove the
spark plug caps from the spark plugs.
Also, put the shift control in Neutral,
put the main switch in the OFF position
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.
8 Do not use your hand to hold the pro-
peller when loosening or tightening the
propeller nut. Put a wood block
between the cavitation plate and the
propeller to prevent the propeller from
turning.

1) Check each of the propeller blades for
wear, erosion from cavitation or ven-
tilation, or other damage.
2) Check the shear pin for wear or dam-
age. The shear pin 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 hap pens, the shear
pin must be replaced.
3) Check for fish line winding around the
propeller shaft. Check the propeller
shaft oil seal for damage.
