It is recommended that the craft be afloat when the

generator set is prepared for storage since the engine

must be started.

1. Add fuel stabilizer to fuel tank. Use

recommendations of fuel stabilizer manufacturer.

2. Start generator set and run until operating

temperature is reached or about 15 minutes. Stop

generator set. Drain oil from crankcase while

engine is still warm. Replace oil filter. Refill

crankcase with specified weight oil.

NOTE

For storage, seawater must be replaced with

antifreezeas describedinsteps 3a--cordrainedas

described in steps 4a--c.

3. Closeseacockandremovehoseatseacock.Place

hose in a container of coolant/antifreeze.

Container should have approximately 1--2 U.S.

gallons (3.7--7.5 L) of antifreeze. A mixture of 50%

ethylene glycol and 50% clean, softened water is

sufficient.

a. With a suitable container at exhaust outlet, run

generator set until coolant discharge is

observed at exhaust outlet or until coolant

mixtureis used up.Donotallow coolant mixture

to flow into waterways. Stop generator set.

b. Connect hose to seacock. Leave seacock

closed.

c. Check coolant level of heat exchanger and add

if necessary.

NOTE

If steps 3a--c were performed to replace

seawater with antifreeze, omit steps 4a--c.

4. Closeseacockanddrainallseawateroutofcooling

withstanding the lowest possible temperatures.

Generally, a mixture of 50% ethylene glycol and

50% clean, softened water is sufficient.

5. Remove spark plugs and pour one teaspoon of

engine oil into each cylinder. Crank the engine

several times to coat the cylinder walls with oil.

Reinstall the spark plugs.

fuel completely from fuel tank. Gum deposits will

develop if gasoline is stored for the season.

7. Clean exterior of generator set and spread a light

film of oil or silicon spray over any exposed

surfaceswhichmaybesubjecttorust or corrosion.

8. Using tape, seal air inlet, exhaust pipe, and fuel

tank cap.

9. Disconnect and remove battery. Battery should be
