Hi guys, My 2.3l OMC runs fine and the temp gauge is mid range when idling the boat on muffs. Put it in the water today and after about 15 mins or so I noticed the temp was slowly climbing. It got just up to almost the red (no actual temp reading) and I shut her down. I have installed a new impeller, I checked the t stat in a pot of hot water before installing it on the new engine and the water pump looked fine also. The water hose coming from the outdrive to the engine is cool and the one that goes to the intake manifold is just warm. The exhaust manifold is cool but the engine block seems pretty warm to the touch! Should I try to flush the engine block somehow? I'm not even sure exactly how cooling system works on this engine. Advice? Thanks
