2.2 Lubrication System
The following paragraphs describe the engine
lubrication system.
2.2.1 Oil Specifications
Use oil that meets the American Petroleum Institute
(API) classification of CC or CD. Using unsuitable oil or
neglecting an oil change may result in engine damage
and a shorter engine life.
2.2.2 Oil Change
Change the engine oil according to the service
schedule. Change the oil more frequently under dirty,
dusty conditions. Change the oil while the engine is still
warm.
See Section 1.2 for oil capacities. See
Section 1.4 , Service View, for the oil fill, oil check, and
oil filter locations.
2.3 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.
Storage Procedure
1. Start and run the generator set until it reaches
operating temperature, about 30 minutes.
2. Stop the generator set.
3. Change the oil and oil filter. See the generator set
operation manual.
4. Drain the seawater from the heat exchanger by
removing the coolant drain plug.
5. 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. Use an environmentally safe marine
antifreeze with corrosion inhibitors.
6. 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.
7. Stop the generator set.
8. Connect the hose to the seacock. Leave the
seacock closed.
9. Check the coolant level in the heat exchanger and
add coolant if necessary.
Note: Use antifreeze with the lowest available
temperature rating.
10. 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.
11. 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.
12. Cover the entire unit with a breathable dust cover.
