2. Install the fuel filter and rotate counterclockwise 1/4 turn to retain the filter.
3. Connect the water‑in‑fuel sensor harness.
NOTE: If there is a boat mounted water‑separating fuel filter with a
water‑in‑fuel sensor installed, the sensor harness would be connected to the
boat mounted filter.
4. Connect the fuel hoses to the fuel filter securely with the locking hose
connections.
5. Turn the key to the RUN position and inspect for fuel leaks. Repair any
fuel leaks if necessary.
Corrosion Control Anode
The outboard has corrosion control anodes at different locations. An anode
helps protect the outboard against galvanic corrosion by sacrificing its metal to
be slowly eroded instead of the outboard metals.
Each anode requires periodic inspection, especially in saltwater which will
accelerate the erosion. To maintain this corrosion protection, always replace
the anode before it is 50% eroded. Never paint or apply a protective coating on
the anode as this will reduce effectiveness of the anode.
