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
filtration 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.
Battery Switch
Your boat uses a battery selector switch located on the
component board just forward of the battery boxes. The
battery selector switch allows you to control the delivery
of DC power from the two batteries.

•
“OFF” - you will
have no power to
the engine.
Be sure engine is stopped
before switching to
“OFF”.
•
“ALL” - you will have
power from both
batteries at the same
time. This parallels the
batteries to assist you, if
necessary, in starting the
engine. Once the
engine is started, the battery switch should
be switched from the “ALL” setting, and
set to charge either battery.
!
WARNING
Use the “ALL” position only if both batteries are
near the same voltage. If one battery is strong
and the other weak, high current could cause
battery damage.
DO NOT operate the boat with batteries in “ALL”
once the engine is started or serious engine
electrical damage may result.
The dual battery switch has four (4) settings, “OFF”,
“ALL”, “1”, AND “2”.
