5. Remove the oil filter by turning the filter counterclockwise. If necessary, carefully move wires temporarily out of the way, to
gain clearance for the oil filter wrench.
6.
Wipe up any spilled oil.
7. Clean the mounting base. Apply a film of clean oil to the filter gasket. Do not use grease. Install the new filter. When the
gasket contacts the base, tighten the filter an additional 3/4 to 1 turn.
8. If any components were moved or removed to gain access to the oil filter, restore them to their original positions or install
them accordingly.
Draining the Engine Oil
1. Lock the outboard in the full tilt up position.
2. Position the outboard so the drain hole is facing downward.
3. Remove the drain plug and drain the 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 install 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 the outboard to the full tilt
position and drain the remaining oil.
