OIL CHANGE ON LAND PROCEDURE
1. Tilt the outboard out/up past vertical for approximately one minute to allow
any trapped oil to drain back to the oil sump.
2. Tilt the outboard to a vertical position.
3. 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.
4. Attach a 12 mm (7/16 in.) inside diameter drain hose to the oil drain valve.
Position the opposite end of the hose into an appropriate container. The
container should be large enough to hold more than 9.8 Liter (10 US qt).
5. Loosen the oil drain valve 2‑1/2 turns to allow oil to drain. Do not exceed
2‑1/2 turns.
IMPORTANT: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.
