1)After shutting off the engine, unscrew the garden-hose connector 2 from the fitting 1 on the bottom cowling.

2)Screw the garden-hose connector 2 onto a garden hose 3 which is con- nected to a fresh-water supply.

3)With the engine off, turn on the water

tap and let the water flush through the cooling passages for about 15 minutes. Turn off the water and disconnect the garden hose 3.

4)When flushing is complete, reinstall the garden-hose connector 2 on the fitting 1 on the bottom cowling. Tighten the connector securely.

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-

NOTE:

8When flushing the engine with the boat in the water, tilting up the engine until it is completely out of the water will achieve better results.

8Refer to cooling system flushing instructions in “TRANSPORTING AND STORING OUTBOARD MOTOR”.
