Fuel leaking from any part of the fuel system can lead
to fire and explosion that can cause serious bodily in-
jury or death. Inspect system before starting engine.
Never enter the engine room without proper ven-
tilation first. A spark caused by power tools or
lighting equipment could result in fire or explo-
sion which could cause personal injury or death.
As with any fuel burning engine Carbon Monoxide is
a concern. Read the Boating Safety section of this
manual, study the pamphlets supplied and educate
yourself about carbon monoxide poisoning. It could
mean the difference in your life and the life of your
loved ones.
2.Check area for fuel fumes. If you detect fuel fumes:
a. Evacuate the boat immediately.
b. Notify the dock, fire department, or Coast Guard of
the condition.
c. Open all hatches, doors, and ports for natural
ventilation.
d. When you can no longer smell fumes, locate
the source. Using a hand held pump, carefully remove
any fuel from bilge. Dispose of this fuel in a safe,
approved location.
3.If you do not smell fuel fumes, make sure fuel shutoff
valve on fuel line to generator is open.
4. Check generator oil level. Refer to the generator
manual for instructions. Add oil if necessary.
5. Check generator coolant level. See generator manual
for instructions.
6. Open generator seacock. Valve is open when handle
is in line with the hose. Seacock is located forward of the
generator sea strainer
7. At generator control panel, turn all 120 Volt circuit
breaker OFF. Make sure slide bar is moved up to lock out
shore power breaker.
8. For Gen Sets other than “Northern Lights” During cold
weather starts place the controllers start/stop switch in
the Stop/Preheat position for 15-20 sec. before attempt-
ing to start the generator.
9. Press and hold in either the remote GENERATOR
START-STOP switch located in the salon or the START-
STOP switch on the generator itself to START. Release
switch as soon as the generator engine begins running.
Important: Do not crank generator continuously for
more than 10 seconds. If engine fails to start within
10 seconds, release switch.
Allow starter motor to
cool for at least 10 seconds. Then try starting the
engine again. If generator fails to start after three
attempts, contact your Mainship dealer. Prolonged
starting attempts may damage starter motor as well
as the generator.
10. Check for water coming from the exhaust outlet
pipe. Water flowing from the pipe indicates the water
is circulating through the generator cooling system. You
should see water flowing shortly after generator starts.
11. Inspect the exhaust system for leaks. If you detect
leaks or smell fumes, shut down the generator
immediately. Do not restart the generator until you have
corrected the problem.
12. Allow the generator to warm up before connecting a
heavy electrical load. Keep the load within the
nameplate rating.
Note: Infrequent use of the generator may result in hard
starting. For detailed start-up information, refer to the
generator operating manual.
8.1.5 Generator Shutdown

f all 120 Volt circuit breakers.
2. Allow generator to run for one to two minutes at no
load to allow the engine to cool down.
3. Press GENERATOR START-STOP switch to STOP.
4. Close fuel valve and seacock.
