Storing outboard motor

When storing your Yamaha outboard motor for prolonged periods of time (2 months or longer), several important procedures must be performed to prevent excessive damage. It is advisable to have your outboard motor serviced by an authorized Yamaha dealer prior to storage. However, you, the owner, with a minimum of tools, can perform the following procedures.

CAUTION:

●To prevent problems which can be caused by oil entering the cylinder from the sump, keep the outboard motor in the attitude shown when transporting

and storing it. If storing or transporting the outboard motor on its side (not up- right), put it on a cushion after draining the engine oil.

●Do not place the outboard motor on its side before the cooling water has drained from it completely, otherwise water may enter the cylinder through the exhaust port and cause engine trou- ble.

●Store the outboard motor in a dry, well- ventilated place, not in direct sunlight.

Flushing in a test tank

1.Wash the outboard motor body using fresh water. For further information, see page 38.

2.Fill the fuel tank with fresh fuel and add one ounce of “Yamaha Fuel Conditioner and Stabilizer” (Part No. LUB-FUELC- 12-00) to each gallon of fuel.
