Mercury Racing 500R - Corrosion Control Anodes

5. Lightly lubricate the fuel filter O‑ring with clean engine oil. Thread the fuel
filter clockwise onto the fuel filter base until the O‑ring makes contact with
the base. Then tighten the filter another 2/3–1 turn.

6. Connect the water‑in‑fuel sensor to the fuel filter sensor harness.
7. Before starting the engine:
a.
Prime the fuel system. Refer to Filling the Fuel System.
b. Inspect the installation for fuel leakage. Repair any fuel leaks if
necessary.
FILLING THE FUEL SYSTEM
Turn the ignition key switch to the RUN position for approximately six seconds
to operate the fuel pumps. Start and operate the engine to purge any remaining
air from the fuel system. The engine may run rough while the air is purging
through the fuel injectors. Purging air may take longer if the vessel mounted
fuel filter is installed further away from the engine. Increasing the throttle during
engine operation will purge air from the fuel system more quickly.
Corrosion Control Anodes
The outboard has corrosion control anodes at different locations. Anodes help
protect the outboard against galvanic corrosion by sacrificing its metal to be
slowly eroded instead of the outboard metals.
