2. Screw the garden hose adapter onto a
garden hose, which is connected to a
fresh water supply, and then connect it to
the garden hose connector.
3. With the engine off, turn on the water tap
and let the water flush through the cool-
ing passages for about 15 minutes. Turn
off the water and disconnect the garden
hose adapter from the garden hose con-
nector.
4. Reinstall the garden hose connector onto
the fitting on the bottom cowling. Tighten
the connector securely.
CAUTION:
ECM00540
Do not leave the garden hose connector
loose on the bottom cowling fitting or let
the hose hang free during normal opera-
tion. Water will leak out of the connector
instead of cooling the engine, which can
cause serious overheating. Be sure the
connector is tightened securely on the fit-
ting after flushing the engine.
NOTE:
When flushing the engine with the boat in the
water, tilting up the outboard motor until it is
completely out of the water will achieve better
results.

Checking painted surface of motor

ing paint. Areas with damaged paint are more
likely to corrode. If necessary, clean and paint
the areas. A touch-up paint is available from
your Yamaha dealer.
