MAINTENANCE & CARE 4
STORAGE
Storing your boat for prolonged periods of time, such as winter storage, requires preventative maintenance to ensure against deterioration. It is advisable to have the boat serviced by an authorized Yamaha Boat dealer before storage. However, the following procedures can be performed by the owner with a minimum of tools.

①Flush Hose Connector
Fuel system
Fill the fuel tank with fresh fuel, adding one ounce of Yamaha Fuel Conditioner and Stabilizer or an equivalent to each gallon of fuel. Do not “top off” the tank, because fuel could spill. 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 the fuel system.
TIP: Use of Yamaha Fuel 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.
②Garden Hose Adapter
Cooling system flushing is essential to prevent the cooling system from clogging up with salt, sand, or dirt.
1)Open the cap for the engine you are going to flush. Press the flush kit garden hose adapter into the flush hose connector and turn until they are securely connected.
2)Start the engine, then immediately turn on the water supply fully.
•Never turn on the water before starting the engine. The water could flow back through the muf- fler into the crankcase causing severe engine damage.
•Be sure to turn on the water imme- diately after starting the engine to prevent engine overheating.
3)Run the engine at a fast idle for 10 to 15 minutes.
