Changing Engine Oil

ENGINE OIL CAPACITY
Engine oil capacity is approximately 800 ml (27 fl. oz.).
OIL CHANGING PROCEDURE
1. Lock the outboard in the full tilt up position.
2. Position outboard so the drain hole is facing downward.
3. Remove drain plug and drain engine oil into an appropriate
container.
IMPORTANT: Do not use a crankcase oil pump when changing
the oil or engine damage may occur.
4. After the initial oil has been drained, temporarily reinstall the
drain plug. Disengage the tilt lock and lower the outboard. Wait
a minute to allow the remaining oil that was trapped in the
engine to return to the drain. Return outboard to the full tilt
position and drain the remaining oil.
