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 outboard motor un- til it is completely out of the water will achieve better results.

●For cooling system flushing instructions, see page 41.
