Hello, I have a 21' runabout i/o and I am wondering about which thermostat I should use. When I search I find a 142 and a 160 degree thermo listed as compatible with my boat's engine. I assume that you can run either one and people have preferences between the two for certain reasons. Would someone please shed some light on this for me? Oh, and if I should post this somewhere else to get more responses, please direct me there. I'm new here. Thank you in advance
