Nobody can answer that using the info you have given, we need more info than that, the more info the better.
What is the KV of the 4082?
How many cells will you be running it on?
Which Proboat hull is it?
That will give people a good guess based on what they would want from the boat, but more info is better.
What sort of speed are you looking for? This ties in with runtime as the bigger the prop the higher the speed and the lower the runtime, but also with the hull as hulls are capable of very different speeds before they start getting out of shape in typical waters, and when they do get out of shape, some are plastic and some are glass so the speeds they can survive a flip at without reinforcing are different, I would guess that you don't want to get into reinforcing your boat for high speeds, but proboats are pretty well engineered for the power they come with so if you want more speed from your big aftermarket motor rather than cooler temps it might be advisable.
You say you are after more than a few passes which is a good start, but what sort of runtime do you want, there is a big difference in the 1-2 minutes a Namba oval racer might assume and the 5-6 minutes a Naviga racer might assume, or you might be filling it with batteries trying to get 10+ mins.
What is your typical water? I run in a 70m X 90m lake with hard sides and trees on 3 banks, it rarely gets windy enough to flip boats with aero, and there is never a swell to launch boats, but it does for pointy little clapotic waves that can
bury noses, and trip boats over. Speeds over about 70mph aren't suitable, and that is only if they turn very well.
