How to video cavitation plate on the water

[maineiac5586]

I don't have anyone to go with me plus I'm trying to keep weight the same in the boat for testing. I believe my motor might be mounted too low. Anyone have suggestions on how to rig a camera to see the cav plate when underway?

GoPro? Cell phone on a (long) selfie stick?

I did some testing with a gopro on high speed so I could slow it down and see the prop. Worked well. Put a safety tether on it. If I had not done that to mine I would have lost it. I wrapped it in a stainless steel .040 safety wire harness I made. I didn't want to trust the gopro lanyard.

Simple.....run a straight edge along the boat bottom and out the back toward the cav plate, with motor tilted in proper running position is the cav plate below the hull ?
