Section 3 • Systems & Components Overview & Operation
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.
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.
Maintenance
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.

Storage
Long periods of storage and/or non-use, common to
boats, create unique problems. When preparing to
store a boat for extended periods, of two months or
more, it is best to completely remove all fuel from
the tank. If it is not possible to remove the fuel,
maintaining a full tank of fuel with a fuel stabilizer
added to provide fuel stability and corrosion
protection is recommended.
• Add fuel stabilizer/treatment at
manufacturers recommended dosage.
• Run engine(s) for 10 minutes.
• Shut OFF fuel valve.
• Allow engine to run util it stops.
• Top off fuel tank, leaving space for
expansion. DO NOT fi ll to point of
overfl ow.
• DO NOT cap the tank vent.
A partially full tank is not recommended because the
void space above the fuel allows air movement that
can bring in water through condensation as the air
temperature moves up and down. This condensation
could potentially become a problem.
