3) Pull fuel shut-off knob next to engine instrument panel until engine stops.
4) When the engine-alarm sounds, turn the key OFF.
IMPORTANT: Do not use the ignition key to shut down the engine. Do not stop the engine with the
decompression levers except in an extreme emergency. If decompression lever is used to shut down
the engine, fuel will spray out and accumulate on top of pistons, creating a danger of explosion the
next time engine is started.
Fueling
When taking on fuel, follow these safety precautions:
1) Secure your boat to the dock using bow, stern, and spring lines.
2) Turn OFF all mechanical and electrical equipment, including the engine, battery selector switch,
cabin lights, and electronics.
3) Remove the fuel-fill deckplate plug; clean the threads of both the plug and deckplate so that no dirt
falls into the filler opening. Place the fuel hose nozzle into the fill pipe.
4) Fill the fuel tank slowly. Do not overfill the tank. Because marine fuel expands with an increase in
temperature, fill the 27-gallon tank you are taking on, to only 95% of its capacity. If you cannot see the
fuel pump, ask the attendant or a crewmember to call out the total gallons.
IMPORTANT: If the fuel tank is overfilled, fuel will spill out of the tank (vent is located on the port side of
the transom). Be ready to contain and clean up any spillage immediately.
5) After fueling, replace the fuel-fill deckplate and clean any spillage. Check belowdeck for fumes and
check the bilge for fuel leakage. If fumes or liquid fuel are present, correct the situation before
proceeding. Open all hatches and ports to ventilate the boat.
IMPORTANT: In the event of a serious fuel spillage, STOP FUELING IMMEDIATELY. Replace the
fuel-fill deckplate and notify the attendant. Wash all traces of fuel or source of fumes; ventilate the
boat. Leave the fuel dock only when you are completely certain that a potentially dangerous condition
does not exist.
When preparing to take on fuel, the following safety precautions should be followed at all times:
Properly secure the boat to the dock using bow, stern and spring lines.
Engine Maintenance
Check the engine, batteries, and engine mounts once a month. Ensure the engine is fastened
securely to the engine mount frames and look for any problems, such as fuel or oil spillage. If you
need help, consult a professional marine mechanic or a Yanmar licensed repair mechanic.
Run the engine frequently and at occasional high speeds, even if it is not in gear. One reason why
sailboat engines may burn out within a few years is that they are run infrequently and lubricating oil is
not thoroughly and evenly distributed on all moving parts. Be sure to check oil and coolant levels
often. If you have any doubts about the purity of the fuel you are buying, use a strainer to filter out
water and dirt.
