5.8 Generator Storage
Perform the generator storage procedure while the craft
is afloat. Follow the procedure below when storing your
generator set for 3 months or more.
Generator Storage Procedure
1. Add fuel stabilizer to the fuel tank of
gasoline-powered generator sets. Follow the fuel
stabilizer manufacturer’s recommendation.
2. Start and run the generator set until it reaches
operating temperature; about 30 minutes.
3. Stop the generator set.
4. Change the oil and oil filter. See the operation
manual.
5. Drain the seawater from the heat exchanger by
removing the seawater zinc anode. See
Section 1.7, Service Views, for location.
6. Close the seacock and remove the hose at the
seacock. Place the hose in a container having
approximately 3.7--7.5 L (1--2 gal.) of marine
antifreeze. Kohler Co. recommends using an
environmentally friendly potable antifreeze such as
PeakR RV/marine propylene glycol/water mix or
equivalent.
7. With a container at the exhaust outlet, run the
generator set until coolant discharges at the
exhaust outlet or until depleting the coolant
mixture. Do not allow the coolant mixture to flow
into waterways.
8. Stop the generator set.
9. Connect the hose to the seacock. Leave the
seacock closed.
10. Check the coolant level of the heat exchanger and
add coolant if necessary.
Note: Use antifreeze with the lowest available
temperature rating.
11. Clean the exterior of the generator set and spread
a light film of oil or silicon spray over any exposed
surfaces which may be subject to rust or corrosion.
12. Remove the spark plugs.
13. Pour one tablespoon of engine oil into each spark
plug hole.
14. Toggle the generator set start/stop switch to crank
the engine two or three revolutions to lubricate the
cylinders.
15. Reinstall the spark plugs and torque them to
specifications.
16. Disconnect and remove the battery. Place the
battery in a dry location for the storage period.
Recharge the battery once a month to maintain a
full charge.
17. Cover the entire unit with a breathable dust cover.
