I am replacing my port side heat exchanger and want to also change thermostat. I have a 2002 340 Sundancer with 8.1S.

Looking for advice on what is the temp rating I need for the thermostat. And good online site that sells them. Thanks

Usually the old thermostat will have markings that tell you the temperature rating

take a look at page 47 in your mercruiser owners manual. It's a 160 degree thermostat
