Storage Procedure

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 antifreeze as described in steps 3a--c or drained as described in steps 4a--c.

3.Close seacock and remove hose at seacock. 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 mixture is used up. Do not allow 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.Close seacock and drain all seawater out of cooling system.

a.Drain seawater from strainer and seawater pump.

b.Remove zinc anode or end cap on heat exchanger, whichever is more convenient, to drain only seawater. Use an air hose to blow out any remaining seawater, if necessary. Check coolant level of heat exchanger and add if necessary.

c.Drain seawater from exhaust waterline.

NOTE

If freezing temperatures will be encountered during storage, be sure engine coolant is capable of 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.

6.If fuel stabilizer was not added to fuel tank, drain 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 surfaces which may be subject to rust or corrosion.

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

9.Disconnect and remove battery. Battery should be placed in a warm, dry location for period of storage. Recharge battery once a month to maintain full charge.

10.Cover entire unit with a dust cover.
