INSPECTION AND MAINTENANCE
Replacing the propeller and shear pin
A worn-out or bent propeller will lower
the motor's performance, and cause
engine trouble.
Before removing the propeller, remove
the spark plug caps from the spark
plugs to protect against personal injury.
�������
!
Do not begin propeller removal and
installation procedure with spark plug
caps attached, shift in forward or
reverse, main switch at other than
"OFF", engine stop cord attached to
the switch, and starter key attached, or
engine could accidentally start leading
to serious personal injury. Disconnect
battery cable if possible.
1 Pull out the split pin from the
propeller boss and remove the
propeller from the shaft.

shaft.

Do not hold propeller with hand(s)
when loosening or tightening propeller
nut. Put a piece of wood block
between propeller blade and anti
ventilation plate to hold propeller.
Notes
• When removing the plug cap cover,
take care not to drop it into the water.
• In order to protect propeller and gears
from damage, shear pin is designed
so as to be broken when propeller
gets strong impact or when the shear
pin is used for a longer period of time.
• Always carry a spare split pin and
shear pin. When the spare has been
used, supply a new one. A damaged
or worn split pin or shear pin should
be replaced with a new one.
�������
!
• Do not reuse split pin.
• After installing split pin, spread the
pin apart to prevent it from falling
out which could lead to the propeller
coming off during operation.
