Corrosion Control Anodes - Mercury 200 Verado FourStroke Operation And Maintenance Manual

9. Open the fuel valve, if equipped.
10. Start the engine and inspect the area for fuel leaks. Repair as required.
NOTE: After replacing the water‑separating fuel filter, the engine may stall or
develop a slight hesitation and should clear itself of entrained air within a few
minutes. Allow the trapped air to be purged from the fuel system before
operating the engine above idle in gear.
Water‑In‑Fuel Warning—Draining the Filter
1. Close the fuel valve, if equipped.
2. Place a container under the fuel filter.
3. Remove the water‑in‑fuel sensor and allow the filter to drain into the
container. The liquid that has drained from the filter must be disposed of
according to applicable regulations and law.
4. Lubricate the sensor O‑ring with clean engine oil.
5. Install the water‑in‑fuel sensor and tighten it to the specified torque.

Corrosion Control Anodes

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 corrosion. To maintain corrosion protection, always replace the
anode before it is completely corroded. Never paint or apply a protective
coating on the anode, as this will reduce the effectiveness of the anode.
