Maintenance
off the water and disconnect the garden
hose adapter from the garden hose con-
nector.

Reinstall the garden hose connector onto
the fitting on the bottom cowling. Tighten
the connector securely. NOTICE: Do not
leave the garden hose connector
loose on the bottom cowling fitting or
let the hose hang free during normal
operation. Water will leak out of the
connector instead of cooling the en-
gine, which can cause serious over-
heating. Be sure the connector is
tightened securely on the fitting after
flushing the engine.
TIP:
When flushing the engine with the boat in the
water, tilting up the outboard motor until it is
completely out of the water will achieve better
results.

the areas. A touch-up paint is available from
