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 refill
with a fresh, dry load of fuel.
FUEL FILTERS
Mercury already provides the appropriate level of filtra-
tion to protect the engine from debris. The addition of
another in-line filter to the system will create a possible
flow restriction that can starve the engine(s) of fuel.
it is advisable to carry extra on-engine filters in case filter
plugging from debris in the fuel tank becomes a problem
during boating.

MAINTENANCE
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 refilling 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.
