I am still new at this also but based on what i been reading from the pros on this forum i would say could be the lines or the stat. Lines could have junk stuck in them maybe a piece of an old impeller or just junk or could be that the thermostat is not opening.

Put it in a big barrel of water once or take it to the lake and see what happens.

Putting it on the muffs does not test the water pump at all, as the hose is force feeding the cooling system.

So, first thing that come to mind is a blockage as stated.

Checked that looks like the rubber grommet has got caught so water was flowing into the caluling and there was a mud nest in the tube which I cleared and im putting a new thermostat in for good measure.
