Whats the best motor selection for an underwater scooter that scuba divers use. I just want to be able to use it within 20 to 25' from the surface. I found this number for underwater pressure 0.433 psi/ft. Also most scooters go 2.5-3.5mph, the cheapest one I found is $200usd called Sea-Doo Aqua Ranger Scooter. I want something fun that goes fast, I have access to sealed boxes and sealed connectors so the controller and batteries can be sealed easily. I have been looking at mechanical seals and I think something like this would be good

because it comes with the lip,

and all I'd need to do is add a backer plate to the shaft so the seal doesnt move backwards on the shaft where it enters the water.
There is also something called the Stuffing Box, but I think the mechanical seal would be better.
Am I going in the right direction here?
