Removing The Propeller; Installing The Propeller - Yamaha E8D Owner's Manual

Maintenance
Check each of the propeller blades for
G
wear, erosion from cavitation or ventilation,
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 shear
pin must be replaced.

CAUTION:
Be sure to use a new cotter pin and bend
the ends over securely. Otherwise the pro-

sion resistant grease to the propeller
shaft.
2. Insert the shear pin into the hole in the
propeller shaft.
3. Align the shear pin with the groove in the
propeller boss, and slide the propeller
over the propeller shaft.
4. Tighten the propeller nut until there is no
forward-and-backward movement.
5. Align the propeller nut hole with the pro-
peller shaft hole.
NOTE:
When the propeller nut does not align with the
propeller shaft hole after tightening it, loosen
the nut to align it with the hole.
