Improper storage of fuel at marinas, limited
boat usage, etc., can cause fuel to become
contaminated. Periodically, it may be neces-
sary to pump accumulating water and con-
taminated fuel from the bottom of the fuel
tank. If the fuel system on your boat becomes
contaminated, contact your dealer or marina
for assistance.
Avoid using fuels with alcohol additives. Alco-
hol blend gasoline will absorb moisture from
the air which can reach such concentrations
that ‘phase separation’ can occur where the
water and alcohol mixture becomes heavy
enough to settle out of the gasoline to the
bottom of the tank. Since the fuel pickup
tubes are near the bottom of the tank, phase
separation can cause the engine to run very
poorly or not at all. Phase separation is more
severe with methyl alcohol and will increase
as the alcohol content increases. Water or
a jelly-like substance in the fuel filters is an
indication of phase separation from the use
of alcohol-blended fuels.
Diesel engine operation requires a good
supply of clean, water-free diesel fuel. Algae
can grow in the accumulated water in the
diesel fuel tank. This will normally occur in
warm climates. Adding a high-quality diesel
fuel additive containing an algaecide may be
required periodically to control algae in your
diesel system, depending on your boating
area. Contact your Tiara Yachts dealer or
engine manufacturer for additional informa-
tion regarding fuels and additives.
