I have a 1983 Newport 28 with a Universal 5411 (raw water cooled). It seems like the engine never gets higher than about 120 deg based on the temp gauge and an infrared thermometer - but the specs say I should be running from 135 to 150. I've replaced the thermostat, the sender, confirmed that the gauge works correctly and know that all of the hoses and water flow are good. When I start the engine I get water out of the
exhaust immediately.
Am I OK here? It seems to me that that I wouldn't see much water out of the
exhaust until the thermostat opens up at 140 deg. I'm wondering why the water out of the
exhaust isn't limited until the temp gauge gets above 140 deg and then the thermostat opens to let water out of the
exhaust and bring new raw water in through the hull inlet.
Anyone with comments or thought are very much appreciated!
