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.
NOTICE:
Do not leave the garden
hose connector loose on the bottom
cowling fitting or let the hose hang
free during normal operation. 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 fitting after flushing the en-
gine.

TIP:
●
When flushing the engine with the boat in
the water, tilting up the outboard motor un-
til it is completely out of the water will
achieve better results.
●
For cooling system flushing instructions,
