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.
