TICE:
Do not leave the garden hose
connector loose on the bottom cowl-
ing fitting or let the hose hang free
during normal operation. Water will
leak out of the connector instead of
cooling the engine, which can cause
serious overheating. Be sure the con-
nector is tightened securely on the
fitting after flushing the engine.

●
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.

more likely to corrode. If necessary, clean
and paint the areas. A touch-up paint is avail-
able from your Yamaha dealer.
