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 pos-
sible.
2. Place a suitable container under the gear
case.
3. Remove the gear oil drain screw and
gasket. The screw is magnetic so a small
quantity of metal particles on the end of
the screw is normal. Simply remove
them. NOTI CE : If there is an excessive
quantity of metal particles on the
magnetic gear oil drain screw, this
can indicate lower unit problem. Con-
sult your Yamaha dealer.
