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.

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.

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.
