Quicksilver 855WE — System & Component Overview and Operaon
Phase Separaon
Humidity and condensaon create water in your fuel tank which can adversely eect the ethanol
blended fuel. A condion called phase separaon can occur if water is drawn into the fuel beyond the
saturaon point. The presence for water in the fuel beyond the saturaon level will cause most of the
ethanol in the fuel to separate from the bulk fuel and drop to the boom of the tank, signicantly
reducing the level of ethanol in the fuel mixture in the upper level (phase). If the lower level (phase),
consisng of water and ethanol, is deep enough to reach the fuel inlet, it could be pumped directly
into the engine(s) and cause signicant problems. Engine problems can also result from the reduced
ethanol/fuel mixture le in the upper phase of the tank.
Addives
There is no praccal addive known that can prevent or correct phase separaon. The only soluon is
to keep water from accumulang in the tank. If phase separaon does occur, your only remedy is to
drain the fuel, clean and dry the tank completely and rell with a fresh, clean tank of fuel.
Fuel Filters
Mercury already provides the appropriate level of ltraon to protect the engine from debris. The
addion of another in-line lter to the system will create a possible ow restricon that can starve the
engine of fuel. As a precauon, it is advisable to carry extra on-engine lters in case lter plugging
from debris becomes a problem during boang.
For vessels powered by L6 Verado(s), Mercury provides an approved, externally mounted fuel lter for
use in your boat. The lter is located above the petrol tank and can be accessed via the cockpit oor
hatch. The lter can be connected to the SmartCra
TM
instrumentaon and will warn you when
maintenance is required. For more informaon, refer to the engine manufacturer’s manual in your
owner’s manual package.
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 re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 protecon is recommended.
REFER TO THE ENGINE MANUFACTURER’S MANUAL IN YOUR OWNER’S MANUAL PACKAGE FOR
COMPLETE INSTRUCTIONS AND WARRANTY INFORMATION.
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.
E85 FUELS COULD SERIOUSLY DAMAGE YOUR ENGINE AND
MUST NEVER BE USED.
Do not obstruct or modify the venlaon system.
