Storage; Fuel System; Fuel Shut-Off Procedure - Yamaha XR1800Z Ower's Manual

STORAGE

Storing your Sport Boat for prolonged
periods of time, such as winter storage,
requires preventative maintenance to
ensure against deterioration. It is advis-
able to have the Sport Boat serviced by
an authorized Yamaha Sport Boat deal-
er before storage. However, the follow-
ing procedures can be performed by
the owner with a minimum of tools.

FUEL SYSTEM

Top off the fuel tank with fresh fuel,
adding one ounce of Yamaha Fuel
Conditioner and Stabilizer or an equiv-
alent to each gallon of fuel. A full fuel
tank is less likely to allow condensation
to collect in the tank, reducing the
chance of contaminated fuel. Running
the engines with treated fuel during
cooling system flushing will also help
protect carburetors and fuel lines.
NOTE: Use
Conditioner and Stabilizer eliminates
the need to drain the fuel system.
Consult your Yamaha dealer or other
qualified mechanic if the fuel system is
to be drained instead.

FUEL SHUT-OFF PROCEDURE

Your Sport Boat is equipped with fuel
supply shut-off valves. When storing
your boat for more than 30 days, it is
recommended that you turn off the fuel
supply valves. This isolates fuel in the
fuel tank and helps prevent contamina-
tion of the fuel system during storage.

AINTENANCE
To turn the fuel supply off, lift the center
passenger seat base cushion. Remove
the fuel shut-off valve access cover by
inserting a flat-bladed screwdriver or
other suitable tool in the cover slot and
prying the cover up. Once the cover is
off, turn both fuel valve levers clockwise
90° until they are perpendicular to the
fuel lines 1.
To turn the fuel supply on, turn each
lever counter clockwise to the in line
position 2. Remember that both valves
must be on for both engines to receive
fuel from the fuel tank.
