Last season I was having problems with some smoke leaking out of the engine around the manifold. I took the manifold off and had to replace one of the studs. I put a new gasket on the manifold and it stopped that problem.
I'm not sure when the exhaust got this bad but this is what it looks like now.

This is with the engine running in forward at about 3/4 power. It will reach temperatures up to 200 and above if I run it like this for longer than 3 or 4 minutes. I removed the thermostat and did an acid flush to try to increase the
Water flow, no help. I left the thermostat off and closed the bypass to force all the water through the engine, that didn't help. The impeller is new as of last fall. I cleaned the water lift muffler no help. The water output seems a little low to me, here it is at idle.

Oil pressure and level remain fine since last change around 3 engine hours ago.
In the first video You can hear a fast knocking or tapping coming from the engine. I think that is a relatively new sound. It only happens when the engine is under load at high rpms. I don't know if the sound and smoke are related. The engine smokes all the time, even at idle. The faster the rpm, the more smoke.
My first question is can anyone confirm, is this steam or smoke? I want to know what troubleshooting road to go down.
Does anyone think the noise and smoke/steam might be related?
Does anyone think the water output is low?
Does anyone have a good idea of what to check next?
Thank you very much, this sight has been a huge help in the past.
