No steam...good. So likely no head gasket issue. Unless there's something seriously wrong with your exhaust system design, you should not be experiencing any water in engine sitting on the dock.

I would hold off on further oil changes until you have fixed the problem. I mentioned previously that it sounds like a water pump seal failure and I still think that, especially since the impeller issue you described.

Either you try a new water pump or you need to gear up and pressure test the block with the water pump removed...if it holds air you know the pump was the issue. If you test with a malfunctioning pump in place it will lose pressure as air is bypassing the seals. Pressure testing with a pump in place have had some people go at the engine looking for cracks etc when the issue is the pump.
