9. GEAR CASE PRESSURE CHECK
• Perform gear case pressure check and check for pressure
leakage after disassembling and reassembling the gear case.
• In principle, the pressure check should be made on the gear
case before filling it with gear oil and before installing it on
the outboard motor. However, the check can be made with
the gear case filled with gear oil.
1) Remove the oil check bolt and the 6.9 x 1.45 mm O-ring.
Replace the O-ring with a new one on reassembly.
2) Install the adapter (special tool) in the oil check bolt hole.
Attach the hose end of the pressure tester S-34 (special
tool) to the adapter.

• Do not screw in the adapter and the hose end with force.
3) While watching the gear case pressure tester gauge, apply
the specified air pressure to the gear case by moving the
handle slowly.
• Do not apply air pressure excessively.
4) While applying the specified air pressure to the gear case,
move the shift rod up and down five or six times.
