allows room for expansion, which will be required at certain times when tempera-
tures increase. The hydrocarbons in gasoline react with naturally occurring oxygen
andcreateaby-productknownas“gum.”Thesubstance,asthenameinfers,plugsup
fuel filters and injectors. Sealing the tank helps reduce gumming by significantly limit-
ing the amount of oxygen available for interaction with the hydrocarbons.
Completely lling the fuel tank prior to storage and then sealing the fuel
tank vent does not allow room for necessary expansion. This can result, in
extreme conditions, in fuel tank rupture. Such release of fuel into the boat
and potentially into the storage area could result in substantial damage to
the boat and contact with any spark (such as a ame-producing pilot light in
a heater) could also result in property damage and serious injury or death.
It is desirable to keep the fuel’s temperature below 80 F. (26 C.) The gumming will
increase as temperatures increase.
Note that fuel stabilizers work ONLY in fresh gasoline. Stabilizers will not cure oxy-
genated gasoline. Adding a stabilizer when the boat is being prepared for outings after
storage will NOT clean the gumming that has occurred or remove water from the fuel
tank or otherwise eliminate any problems that have occurred due to failure to properly
prepare the fueling system for storage.
 ILMORsuggestsusingFederalorStateofCalifornia(TOPTIER)reformulatedgaso-
line whenever possible as it stores as well or better than conventional gasoline.
Even quality gasoline that has been properly prepared for storage should never
be stored for a period to exceed one (1) year.
Fuel systems on all boats equipped with ILMOR MV-8 engines MUST be
properly prepared for storage periods exceeding two (2) weeks, as outlined
in this Owner’s Manual. Failure to do so will void the warranty.

DRAINING. The ILMOR 50/50 coolant will provide freeze protection down to -26 F.
(-32 C.) All components which raw water flows through must be drained. The following
steps are recommended for draining of raw water components:
