WARNING

●Make sure that the outboard motor is mounted securely to the transom or a stable stand. You could be severely in- jured if the outboard motor falls on you.

●Never get under the lower unit while it is tilted. Severe injury could occur if the outboard motor accidentally falls.

Before filling the lower unit with gear oil, the outboard motor must be placed in a vertical position. If you are not able to place the outboard motor in a vertical position, have a Yamaha dealer change the gear oil.

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