At Least Annually
(performed by a qualified marine technician)
• Replace exhaust hoses if any evidence of cracking, charring or
deterioration is found.
• Replace each water pump impeller and inspect the condition of
the water pump housing. Replace if worn.
(Refer to the engine
and generator manuals for further information.)
• Inspect each of the metallic exhaust components for cracking,
rusting, leaking or looseness. Pay particular attention to the
cylinder head, exhaust manifold, water injections elbow, and the
threaded adapter nipple between the manifold and the elbow.
• Clean, inspect and confirm the proper operation of the generator
cooling water anti-siphon valve
(if equipped)

Fuel System
Everyone who owns or operates a boat must practice fire safety.
Each year, boat fires and explosions injure hundreds of individuals
and cause millions of dollars in property damage. Many of these
accidents can be prevented.
Be alert for damage to your boat’s fuel system. Over time, fuel fit-
tings and fuel hoses wear out. Inspect these fittings and hoses
regularly, especially near the engine where engine heat and vibra-
tion can accelerate deterioration.
What to do
1. Schedule regular engine and exhaust system maintenance
inspections by experienced and trained technicians.
2. Inspect fuel systems annually, particularly hoses, connections
and tank surfaces. Use only USCG-approved fuel hoses.
3. Before fueling, shut down engines and auxiliary equipment and all
electrical equipment. Also close all hatches and doors on board.
4. Do not allow equipment or gear to contact fuel-system compo-
nents. Monitor side storage areas where fill and vent hoses are
often located.
5. Do not store portable fuel tanks in enclosed areas, including the
engine room compartment (even though it may be “ventilated”).
6. If your boat is equipped with a ventilation system, ensure that all
blowers and hoses are operational and intact. Verify good air-
flow at the vent located on the boat.
7. Take a boating safety course and learn the correct type and use
of a fire extinguisher aboard a boat.
Each Trip
• Before starting the engine “sniff” your bilges. Getting down on your
hand and knees and using your nose is the best fuel/vapor detector.
• Operate the bilge blower for AT LEAST FOUR MINUTES before
starting an inboard or sterndrive engine. If you still smell fumes, try
to locate the source and make repairs before starting the engine.
• Make sure all passengers know where to find your fire extin-
guishers and how to operate them.
• Before refueling, close all hatches, ports and other openings;
shut off engines, motors, pumps and blowers; and DO NOT
SMOKE. Fill all portable tanks on the dock.
