Corrosion Control Anode
Your outboard has a corrosion control anode installed to the gear case. An anode helps pro-
tect the outboard against galvanic corrosion by sacrificing its metal to be slowly eroded in-
stead of the outboard metals.
The anode requires periodic inspection especially in salt water which will accelerate the ero-
sion. 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 effective-
ness of the anode.

Spark Plug Inspection
Inspect spark plugs at the recommended intervals.
1. Remove the spark plug leads by twisting the rubber boots slightly and pull off.
2. Remove the spark plugs to inspect and clean. 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 reinstalling spark plugs, clean away dirt on the spark plug seats. Install plugs fin-
ger tight, and tighten 1/4 turn or torque to 13 lb-ft (17.5 Nm).
