Thanks Alan. It still amazes me how harsh the marine environment
must be for the amount of stuff that fails on sail boats. If I replace the thermostat, that'll be the third component to have failed in the path to getting the temperature gauge functional. First, the gauge had a bad ground. Replaced the wire. Next, the gauge was faulty. Replaced the gauge. Then, the gauge finally started working but read low (125F max). I suspected a bad sender since it was all corroded. Well, that was a waste of money
. Anyway, I hope a new thermostat solves the problem. After that, it'll probably be some oil
pressure relief valve or something
Are these cascading failures signs of poor maintenance
by the previous owner or just a signs of a 20 year old boat?
