Procedure

Engine Oil Drain

1. Tilt the outboard to a vertical position. 2. Use a 16 mm (5/8 in.) wrench and loosen the oil drain valve so that it can be turned by hand. Be careful not to open the valve too far allowing oil to drain. 3. Attach a 12 mm (7/16 in.) I.D. drain hose to the oil drain valve. Position the opposite end of the hose into an appropriate container. 4. Loosen the oil drain valve 2‑1/2 turns to allow oil to drain. Do not exceed 2‑1/2 turns. WARNING: Do not loosen the oil drain valve more than 2‑1/2 turns out. The oil seal could get damaged beyond 2‑1/2 turns. 5. After the oil has drained, hand‑tighten the oil drain valve clockwise and remove the oil drain hose. 6. Tighten the oil drain valve to the specified torque (15 Nm / 133 lb‑in.). Clean up any oil in the valve area. (torque: 15 Nm) WARNING: Overtightening the oil drain valve can damage the oil sump. Tools: 16 mm (5/8 in.) wrench, 12 mm (7/16 in.) I.D. drain hose, appropriate drain container
