On the coast of North Carolina sitting at the slip running for that time at about 1500-2000rpm. Next weekend I’m moving the boat about 6 miles, probably motoring most of that so I’ll keep an eye on it. There wouldn’t be away for water to by pass circulating through the engine if the thermostat malfunctioned would there? I don’t think so. It is raw water cooled.
