WARNING

●Be sure the outboard motor is securely fastened to the transom or a stable stand. You could be severely injured if the outboard motor falls on you.

●Never get under the lower unit while it is tilted, even when the tilt support lever or knob is locked. Severe injury could oc- cur if the outboard motor accidentally falls.

1.Tilt the outboard motor so that the gear oil drain screw is at the lowest point possi- ble.

2.Place a suitable container under the gear case.

3.Remove the gear oil drain screw and gas- ket. NOTICE: If there is an excessive quantity of metal particles on the mag- netic gear oil drain screw, this can in- dicate lower unit problem. Consult your Yamaha dealer. [ECM01900]

TIP:

●If a magnetic gear oil drain screw is equipped, remove all metal particles from the screw before installing it.

●Always use new gaskets. Do not reuse the removed gaskets.

4.Remove the oil level plug and gasket to allow the oil to drain completely.

NOTICE: Inspect the used oil after it has been drained. If the oil is milky, water is getting into the gear case which can cause gear damage. Con- sult a Yamaha dealer for repair of the lower unit seals. [ECM00711]

TIP:

For disposal of used oil, consult your Yamaha dealer.

5.Put the outboard motor in a vertical posi- tion. Using a flexible or pressurized filling device, inject the gear oil into the gear oil drain screw hole.
