FUEL LINE INSPECTION

Visually inspect the fuel line and primer bulb for cracks, swelling, leaks,

hardness,  or  other  signs  of  deterioration  or  damage.  If  any  of  these

conditions are found, the fuel line or primer bulb must be replaced.

Propeller Replacement

!

 WARNING

If the propeller shaft is rotated while the engine is in gear, there is the

possibility that the engine will crank over and start. To prevent this type

of  accidental  engine  starting  and  possible  serious  injury  caused  from

being  struck  by  a  rotating  propeller,  always  shift  outboard  to  neutral

position  and  remove  spark  plug  leads  when  you  are  servicing  the

propeller.

1. Remove the spark plug lead to prevent engine from starting.
