Flushing Device
Y o u r Y a m a h a
outboard features a
fl ushing device which
when connected to a
garden hose circulates
fresh water through
the engine to purge
unwanted debris such
as found in salty,
brackish, and silty
water.

Notice there is a
garden hose bib thread. Attach the male end of a garden hose to
the
fi tting and tighten it. Make sure the fi tting does not leak as the
powerhead could overheat and cause internal damage. It is best to
perform this fl ushing procedure with the engine still warm from a
cruise as the thermostat will be open and will permit more effi cient
water circulation.Turn on the fresh water supply. When fl ushing
completed remove the garden hose from the fi tting and reattach the
hose connections and of course check for tightness.
Note: Do not start engine during this procedure as overheating
and possible engine damage may occur.
