Replacement:
1) Place the outboard motor on a level surface and tilt up the
outboard motor.
2) Remove the oil level bolt and the oil drain bolt, and drain
the old oil.
Replace the O-rings on assembly.
If there is water in the oil, the water will flow out first when
the oil drain bolt is removed, or the oil will be a milky color.
If water in the gear oil is detected, check the gaskets and
water seals for damage, and check the torque on the gear
case bolts.
3) Check for the metal particles on the magnet end of the oil
4) If there are metal particles on the magnet end of the oil
drain bolt, disassemble the gear case assembly and check
(See section 14).
5) Install a commercially available gear oil pump in the oil
drain bolt hole, and add gear oil until it flows out of the oil
level bolt hole.
6) After adding the gear oil, apply clean engine oil to the new
O-rings and install them on the oil drain bolt and the oil
level bolt.
Set the oil drain bolt and the oil level bolt on the gear case,
and tighten the bolts to the specified torque.
