I agree with the weighted tripod/ camera mount suggestions.
I'm not familiar the different Go Pro models, but could having the camera "on its side" give you more of the shaped frame that you want?
Finally, while I'm not sure if you need this suggestion: to stay "in frame" for the video, take a few test shots, where you have marked your distance from the camera (using a tape plastic measure?), and for the actual drill shot, try to stay at the distance that you prefer. (The distance would probably depend on the drill you are trying to video.)
Much easier to do this for a land based video, a bit easier near a pool bottom (where you could place a marker at the desired distance), but it might help.
Good luck with your video.
