Section 3 • Systems & Components Overview & Operation
If phase separation does occur, your only remedy is
to drain the fuel, clean and dry the tank completely
and refi ll with a fresh, dry load of fuel.
Fuel Filters
Mercury already provides the appropriate level of
fi ltration to protect the engine from debris. The
addition of another
in-line fi lter to the system will
create a possible fl ow restriction that can starve the
engine(s) of fuel.
As a precaution, it is advisable to carry extra
on-engine fi lters in case fi lter plugging from debris in
the fuel tank becomes a problem during boating.
Periodically inspect for the presence of water in the
fuel tank. If any is found, all water must be removed
and the tank completely dried before refi lling the tank
with any fuel containing ethanol.
Fuel Systems with Portable tanks:
Most portable fuel tanks have closable vents. Close
the vent while in storage to prevent air from entering
the tank.
Long periods of storage and/or non-use, common to
boats, create unique problems. When preparing to

The use of fuels containing ethanol higher than
10 percent (E-10) can damage your engine and/
or fuel system and will void the warranty.

Storage
Your boat was manufactured, and shipped from the
factory, with ethanol-compatible materials. Before
introducing gasoline with ethanol into your fuel
tank, ask your dealer if any components have been
added or replaced that are not recommended by
Boston Whaler, Mercury or may not be ethanol-
compatible.
Filling The Tank
It is best to maintain a full tank of fuel when the
engine is not in use. This will reduce air fl ow in and
out of the tank due to changes in temperature as
well as limiting exposure of the ethanol in the fuel
to humidity and condensation.
Phase Separation
Humidity and condensation create water in your fuel
tank which can adversly effect the ethanol blended
fuel. A condition called phase separation can occur
if water is drawn into the fuel beyond the saturation
point. The presence of water in the fuel beyond the
saturation level will cause most of the ethanol in the
fuel to separate from the bulk fuel and drop to the
bottom of the tank, signifi cantly reducing the level of
ethanol in the fuel mixture in the upper level (phase).
If the lower level (phase), consisting of water and
ethanol, is deep enough to reach the fuel inlet, it
could be pumped directly to the engine(s) and cause
signifi cant problems. Engine problems can also result
from the reduced ethanol/fuel mixture left in the
upper phase of the tank.
Additives
There is no practical additive known that can prevent
or correct phase separation. The only solution is to
keep water from accumulating in the tank.
