FUSE REPLACEMENT - ELECTRIC START REMOTE
CONTROL MODELS
IMPORTANT: Always carry spare SFE 20 AMP fuses.
The electric starting circuit is protected from overload by a SFE 20 AMP fuse. If
the fuse is blown, the electric starter motor will not operate. Try to locate and
correct the cause of the overload. If the cause is not found, the fuse may blow
again. Replace the fuse with a fuse of the same rating.
1
Replace with a new SFE 20 AMP fuse.

CORROSION CONTROL ANODE

Your outboard has a corrosion control anode installed to the gear case. An anode
helps protect the outboard against galvanic corrosion by sacrificing its metal to be
slowly eroded instead of the outboard metals.
2
The anode (a) requires periodic inspection especially in salt water which will
accelerate the erosion. To maintain this corrosion protection, always replace
the anode before it is completely eroded. Never paint or apply a protective
coating on the anode as this will reduce effectiveness of the anode.

PROPELLER REPLACEMENT

WARNING
If the propeller shaft is rotated while the engine is in gear, there is the pos-
sibility 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
Shift the outboard to neutral position.
2
Remove the spark plug leads to prevent engine from starting.
3
Place a block of wood between gear case and propeller to hold propeller and
remove propeller nut.
4
Pull propeller straight off shaft. If propeller is seized to the shaft and cannot be
removed, have the propeller removed by an authorized dealer.

PROPELLER REPLACEMENT (CONTINUED)
5
Coat the propeller shaft with Quicksilver or Mercury Precision Lubricants
Anti-Corrosion Grease or 2-4-C Marine Lubricant with Teflon.
IMPORTANT: To prevent the propeller hub from corroding and seizing to the
propeller shaft, especially in salt water, always apply a coat of the
recommended lubricant to the entire propeller shaft at the recommended
maintenance intervals and also each time the propeller is removed.
6
Flo-Torque I Drive Hub Propellers - Install forward thrust hub (a), propeller (b),
rear thrust hub (c) and propeller nut (d) onto the shaft.
7
Flo-Torque II Drive Hub Propellers - Install forward thrust hub (a), replaceable
drive sleeve (b) propeller (c), rear thrust hub (d) and propeller nut (e) onto the
shaft.
8
Place a block of wood between gear case and propeller and tighten propeller
nut.

SPARK PLUG INSPECTION AND REPLACEMENT
Avoid serious injury or death from fire or explosion caused by damaged
spark plug boots (a). Damaged spark plug boots can emit sparks. Sparks
can ignite fuel vapors under engine cowl. To avoid damaging spark plug
boots, do not use any sharp object or metal tool such as pliers, screwdriv-
er, etc. to remove spark plug boots.
1
Remove the spark plug leads by twisting the rubber boots slightly and pull off.
2
Remove the spark plugs to inspect. Replace spark plug if electrode is worn or
the insulator is rough, cracked, broken, blistered or fouled.
3
Set the spark plug gap. See Specification Chart in General Information Section.
4
Before installing spark plugs, clean away dirt on the spark plug seats. Install
plugs finger tight, and tighten 1/4 turn or torque to 20 lb. ft. (27 N·m).
