CLEANING COOLING-WATER PASSAGES

Flushing device equipped model

Perform this procedure right after operation for the most thorough flushing.

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.

CAUTION:

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 fitting after flushing the engine.

NOTE:

●When 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.

●Refer to cooling system flushing instruc- tions in “TRANSPORTING AND STOR-

ING OUTBOARD MOTOR”.
