● 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
occur if the outboard motor accidental-

2. Place a suitable container under the
gear case.
3. Remove the cooling water inlet covers

the magnetic gear oil drain screw,
this can indicate lower unit problem.

case may be damaged. Have a
Yamaha dealer check and repair the
outboard motor.
