fl ushing device which
when connected to a
garden hose circulates
fresh water through
the engine to purge
unwanted debris such

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. Next, turn on
the fresh water supply. Start the engine and run in neutral idle speed
only. Let the engine warm up enough so that the thermostat opens
and permits purging of the powerhead cylinder water jackets. If the
thermostat is not open the cylinder head areas normally are bypassed.
When
fl ushing completed remove the garden hose from the fi tting
and reattach the hose connections and of course check for tightness.
