BOAT-MOUNTED FUEL FILTER
The boat‑mounted fuel filter can be serviced as a general maintenance item
when the water‑in‑fuel alarm is activated.
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.
