CLEANING COOLING-WATER
PASSAGES
Flushing device equipped model
Perform this procedure right after opera-
tion for the most thorough flushing.
1) After shutting off the engine, unscrew
the garden-hose connector 2 from
the fitting 1 on the bottom cowling.
2) Screw the garden-hose connector 2
onto a garden hose 3 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. Turn off the water and dis-
connect the garden hose 3.
4) When flushing is complete, reinstall
the garden-hose connector 2 on the
fitting 1 on the bottom cowling.
Tighten the connector securely.
cC
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.
