6. Flush the sea water circuit with fresh water and then run an antifreeze mixture through the sea water
circuit to protect it against freezing.
NOTE: Feed the sea water circuit out of a 5-gallon bucket to flush both the circuit and supp-
ly it with an antifreeze mixture.
Fogging the engine should be done as the last of the antifreeze mixture is drawn into the sea water cir-
cuit. Remove the air intake screen (the air filter) and spray Marvel Mystery Oil or another commercial-
ly available fogging oil into the carburetor while the engine is running. Spray enough oil to stall the
engine. This will coat the walls of the cylinders, pistons, and valve surfaces with this protective oil.
Remove the spark plugs and spray a small amount of this oil into each spark plug hole and turn the en-
gine over two or three complete revolutions by hand. Reinstall, but do not tighten, the spark plugs as
these will need to be cleaned and gapped prior to recommissioning. Close off the carburetor's air fil-
ter with an oily rag.
7. Remove the impeller from the sea water pump and inspect its condition. Do not reinstall the impeller
in the pump until the engine is recommissioned.
8. Check the alternator and the sea water pump's drive belts.
9. Ensure that the fuel tanks are near full. When filling the fuel tanks, add any gasoline stabilizers, con-
ditioners or carburetor conditioners that are desired. Please follow the additive manufacturer's instruc-
tions.
10. Lubricate the linkage between the carburetor throttle and the governor arm.
11. Remove the starter motor and clean and lubricate the drive pinion.
NOTE: Remove the DC power to the engine prior to removing the starter motor.
12. Check over the engine and see if external items, such as hoses or belts, will need replacing come
recommissioning. Check over your basic spares kit and order those items not on hand or that were
used during this lay-up, such as filters and zinc anodes.
13. The generator engine's starting battery, if left on board during this lay-up period, should be in a full
charged state to prevent the battery from freezing. If the battery is not fully charged, it is wise to remove
the battery and place it in a warmer location.
NOTE: For a more detailed description of the End-of-Season Service instructions, see the
Operator's Manual.
