So sports fans. I have replaced the impeller, the water pump, the sensor units, and the thermostat, and replaced the original wet joint manifold/spacer/and riser with a brand new Dry Joint Manifold manifold/spacer/and riser. Also replaced the plugs and cables, while I had the manifolds off, so this boat sounds amazing... But she is still overheating and I am lost.
Yes, I backflushed the system too. Also, the Manifolds are getting hot too like water is not getting to them. I need help, any ideas? Could something be clogged in the upper stern drive unit? Or the barrings under the impeller shot?
