I have a 28'-0" Searay
I have a 28'-0" Searay Sundnacer with twin small block v-8 mercruiser engines. The right engine is overheating. So far the impellor has been replaced along with the circulating pump. The engine gets warm during idle but will not over heat. When both engines are running and the rpms are increased to plane the boat off the temperature steadily rises and the engine overheats. If you run the right engine only at full throttle the engine does not over heat but the boal will not plane off either. Weird! Any ideas?
