Brushless motors oil filled

[orangeltr456]

So i have been reading around, For my newest project I need to be able to dive 150 ft in sea water. I want to use brushless because of higher power and motor controllers are cheep compared to brushed. The problems is I dont have a lathe so building a housing is going to be a real challenge, Optimally I would like to have geared down inrunner with magnetic coupling bit could settle for sealed as long as it would be reliable at 150ft. I have a pretty good budget if someone is wiling to make them. I wuld gladly make them if I had acsess to a lathe but that will have to wait a while. Any suggestions,

plan on using 5 motors because my rov will weigh about 35 lbs. so the stronger the better.

I have a mill and lathe if you'd like I can help you out. I design and prototype pneumatic valves, but have no experience programming. Maybe we can help each other?
