Impeller/ Water Pump
Periodically, the coolant system’s impeller and water pump should
be inspected for debris, damage or excessive wear due to use, water
chemistry such as mineral and/or silt conditions. Damaged parts will
affect the system’s ability to function, and may cause engine overheating
or damage. Contact your closest Regal dealer for more information
and maintenance schedules of key outboard engine systems.
Thermostat
If the temperature gauge starts yielding abnormal readings, it may
become necessary to look at or replace the powerhead thermostat after
determining whether it is functioning properly. The thermostat reads
the temperature of coolant and determines whether to open or close a
valve to allow warm sea water to pass into the exhaust manifold. The
thermostat may recirculate hot coolant for the purposes of reaching
standard operating temperatures. If standard operating temperatures
have been reached, the thermostat will open a valve and allow hot raw
water to exit through the exhaust manifold. For more information
read your outboard engine manual or contact the closest Regal dealer
