Treatment
Proper storage and/or winterization
tant as how a drive train is maintained in use. Since special preparations are necessary, the
boat owner should have the work done by an ILMOR-authorized dealer. Damage that oc-
curs from improper storage and/or winterization is not covered under warranty and must
be avoided.
Engine winterization requires adding a fuel stabilizer and biocide to the fuel tank/sys-
tem, changing the engine oil/filter, draining all raw water from the cooling system, and
adding marine/RV anti-freeze to all raw water engine components.
Damage due to improper storage and/or winterization preparations is not cov-
ered under warranty. Owners are encouraged to seek assistance from an authorized
ILMOR dealer to properly prepare the drive train for periods of inactivity exceeding
two (2) weeks.
This preparation needs to be done prior to removing water from the engine, if that will be part of
the process.
Boats that are going to be stored
periods (more than two [2] weeks) or winterized should have atten-
tion for the fuel system. Even TOP TIER gasolines will experience
some separation of elements and settling during these periods. Of
considerable concern is that water condensation will occur within
the fuel system, and water is an enemy of good-starting and running
engine fuel systems. T herefore, follow this procedure:
• The fuel tank should be ninety-to-ninety-five percent (90-95%)
full of TOP TIER gasoline. This allows for minimal room in which
air can oxygenate the fuel during diurnal cycles (daily periods of
expansion/contraction of gasoline vapors and air as a result of tem-
perature changes). As temperatures rise in the tank, the pressure
also rise, pushing out gasoline vapor-and-air mixtures. When the
temperature falls, pressure lowers and the system will seek to draw fresh air and water vapor
(depending on the humidity level) into the tank. Fresh air is replaced with "light ends," which
are low-boiling components that vaporize at ambient temperatures. Light ends are required
during cold starts to vaporize the fuel. Since the daily diurnal cycles eliminate the light ends,
a nearly full tank helps to minimize the air volume entering the system.
• Add a biocide additive such as V alvetect Bioguard
crobial growth in gasoline. Follow the directions provided by the stabilizer's manufacturer.
• Add a fuel stabilizer, such as Sta-Bil
by the stabilizer's manufacturer.
