Yes, like Cajuncook says, was your post meant to be instructional or are you asking for advice?
Many an impeller are ruined trying to barrel test outboards, oftentimes the gearcase is not deep enough in the water for the impeller to prime, letting it run dry and get melted. It is critical that the water level is above the gearcase/exhaust housing joint to avoid problems.
Barrel testing a large engine like this doesn’t confirm much, except that the engine runs (at low speeds) and pumps water….Don’t attempt to make any final adjustments in a barrel, save that procedure for when the engine is on the boat running in the water. Your stand looks pretty sturdy, but I fear that most folks watching your video/demo would settle for something much weaker/less sturdy, which usually ends up damaging the engine/owner when it falls over….That is a big/heavy engine….
