VESSEL MOUNTED WATER-SEPARATING FUEL FILTER
This engine requires a vessel mounted water‑separating fuel filter. The filter
should be replaced annually or every 100 hours, whichever occurs first.
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.
Filter Replacement
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.
