Water‑Separating Fuel Filter
Fuel is flammable and explosive. Ensure that the key switch is off and the lanyard is positioned so that the engine cannot
start. Do not smoke or allow sources of spark or open flame in the area while servicing. Keep the work area well ventilated
and avoid prolonged exposure to vapors. Always check for leaks before attempting to start the engine, and wipe up any
spilled fuel immediately.
Water entering the fuel injection system will cause corrosion and rusting of the injectors and other components, disabling the
fuel injection system. Check daily for water in the water‑separating fuel filter and have the engine inspected immediately if
there is evidence of water in the fuel system.
IMPORTANT: Use a suitable container to collect fuel. Clean up any spills immediately and dispose of fuel in a safe manner in
accordance with all local, federal, and international regulations.
The engine‑mounted water‑separating fuel filter is equipped with a water‑in‑fuel (WIF) sensor that should alert the operator
when water is present in the filter. This fuel filter needs to be replaced at specified intervals or whenever water is detected in
the fuel, whichever comes first.
The operator may be alerted that the WIF sensor has detected water in the fuel, depending upon the boat instrumentation
package and if equipped:
•
A fault code may be displayed on a system viewer.
•
The audio warning system may sound.
See Features and Controls.
Drain or replace the remote mounted primary filter (such as a Racor® filter) at specified intervals, or whenever water is
detected in the engine‑mounted fuel filter.
Draining
The engine‑mounted water‑separating fuel filter can be drained of water and small dirt particles by opening the drain cap on the
bottom of the filter.
NOTE: To ensure complete draining in warm weather, drain the filter before starting daily operations. In cold weather, where
there is a possibility that the condensed water will freeze, drain the filter shortly after the end of daily operations.
NOTE: Place a suitable container under the fuel filter to catch contaminated fuel or water. Dispose of properly.
