RECOMMISSIONING AFTER STORAGE/
WINTERIZATION
Properly preparing the engine and drive train aer a period of storage and/
or winterization is equally important. Equal attention must be paid to the
same components during recommissioning as during the winterization
process.
NOTE: When putting the engine back into service aer winterization or long-
term storage, perform the procedures listed in Section 4, Before Each Use.
1. Remove raw water pump impeller and check it carefully. If it appears
to have weathered or there are any doubts about its ability to function
properly, replace it.
2. Check all uids: oil, transmission, cooling.
3. Reinstall battery(ies) and check the battery voltage. With the key on,
but before the engine is started, the voltmeter should read above 12
volts. If it is less, charge the battery(ies).
NOTE: All Ilmor High-Performance engines are equipped with additional
wires for a Clean Power connection. e MV10 engines also have a Clean
Ground connection. ese wires must be connected directly to the respective
battery that powers each engine. Otherwise, the engines will not crank.
4. Visually inspect the fuel system. If there appears to have been undue
weathering or any leaks have appeared over the storage/winterization
period, contact your authorized Ilmor High-Performance Marine
service center for correction. DO NOT start the engine if there is any
appearance of leakage or rupture of any component of the fuel system.
5. Install boat hull drain plugs.
6. Marine/RV antifreeze should be drained and recycled. It is best
accomplished by running the boat on the garden hose and collecting
the antifreeze into buckets as it comes out of the exhaust.
7. Review the boat manufacturer’s storage and winterization
recommissioning directions to ensure that all requirements have been
met, prior to launching the boat.
