Removing The Propeller - Yamaha 50 Owner's Manual

the battery cut-off switch if your boat
has one.
Do not use your hand to hold the pro-
G
peller when loosening or tightening the
propeller nut. Put a wood block be-
tween the anti-cavitation plate and the
propeller to prevent the propeller from
turning.
Checkpoints
Check each of the propeller blades for
G
wear, erosion from cavitation or ventila-
tion, or other damage.
Check the propeller shaft for damage.
G
Check the splines / shear pin for wear or
G
damage.
Check for fish line tangled around the pro-
G
peller shaft.
Check the propeller shaft oil seal for dam-
G
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
ZMU01896
shear pin must be replaced.
