CHECKING PROPELLER
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 posi-
tion 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 ventila-
tion, or other damage.
2) Check the splines for wear and damage.
3) Check for fish line winding around the
propeller shaft.
Check the propeller shaft oil seal for
damage.
