    Don Thermostat

    Don on a 7 year old 150 (sn1B947225) with 400 hours do you recommend changing the thermostat as a preventive maintenance item?

    I would base replacement on an inspection (and test) of the thermostat. If it does not close properly, open properly, or exhibits any corrosion: REPLACE it.

    Inspection/testing of the thermostat is part of the Annual Maintenance.
