11. CLEANING AND FLUSHING
After each use in salt water or dirty
water, thoroughly clean and flush the
outboard motor with fresh water.
Do not apply water or corrosion
inhibitor directly to the electrical
components under the engine
cover, such as the O2 sensor. If
water or corrosion inhibitor
penetrates this component, it may
be damaged. Before applying a
corrosion inhibitor, cover the O2
sensor with a protective material to
prevent damage.
Shut off the engine before performing
the cleaning and flushing.
1. Disconnect the fuel line from the
outboard motor.
2. Tilt down the outboard motor.
3. Clean and wash the outside of the
outboard motor with fresh water.
4. Disconnect the flush port
connector.
5. Screw the flush port connector onto
the garden hose.
6. Turn on the fresh water supply and
flush the outboard motor for at
least 10 minutes.
7. After flushing, disconnect the
garden hose and reconnect the flush
port connector.

move the tilt lock lever to the
LOCK position.
