Step 1: Precautions
General Precautions
Refer to “General Precautions” in Section 00 (Page 00-1).
Precaution for Lower Unit
• When installing or removing the propeller, shift into “Neutral” and remove the emergency stop switch lock plate so that the motor cannot be started accidentally.
• Wear safety glasses if using compressed air.
• When draining lower unit gear oil, check the following points.
– Water ingress (white, milky appearance)
– Overheating or burning (black appearance, charred smell)
– Metal filings or deposits
• If reassembling with original components and gears, do not omit or add any shims or thrust washers.
To simplify reassembly and to prevent confusion, note the positions and quantities of all shims and thrust washers. Retain these items next to the gears or bearings to which they belong.
