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.

between the cavitation plate and the
propeller to prevent the propeller from
turning.

wear, erosion from cavitation or ven-
tilation, or other damage.
2) Check the splines for wear and dam-
age.
3) Check for fish line winding around the
propeller shaft. Check the propeller
shaft oil seal for damage.
