Flushing power unit

Perform this procedure right after operation

for the most thorough flushing.

1. After shutting off the engine, unscrew

the garden hose connector from the fit-

ting on the bottom cowling.

2. Screw the garden hose connector onto a

garden hose which is connected to a

fresh water supply.

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.

4. When flushing is complete, reinstall the

garden hose connector on the fitting on

the bottom cowling. Tighten the connec-

tor 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 un-

til it is completely out of the water will

achieve better results.

●

For cooling system flushing instructions,

see page 41.
