Checkpoints
Check each of the propeller blades for
wear, erosion from cavitation or ventila-
tion, 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.
