Yeah, I would raise the water level in that bucket a bit so the gearcase to extension hsg joint is completely submersed.  I see alot of steam coming out of the exhaust relief, is there any water in the steam spray?  How long was the engine running when you made the video?  Did it appear to be getting hot?   Yes, it is fairly normal for these engines to steam a bit, but it could also be overheating as well.
