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.

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.
1. Place a container under the drain cap on the filter.
2. Open the drain by turning the drain cap counterclockwise (as viewed from the bottom of the filter) until fuel starts draining.
Do not remove the drain cap.
