Ok, I'm going to go out on a limb here and I'm going to say a 120A speed control or above. The 25amp unit will melt. The 7700s pull some serious amps. I generally have to gear way down just to get the mamba to 180 degrees on my offroad vehicles. In my opinion the 7700s are for on road only. At 2S you are looking at 56k rpm about double what a boat would normally pull. I think you are going to smoke some esc with this one. I think the 7700's will work on 3 or 4 nimh cells each. The villain also doesnt have any prop choices so you are stuck with whats on it right now. The only way I think you could get it to work is if you could prop way down. If you can gear it to about half of what the titans normally geared at you may have a chance on this one, but even at that I would recommend an 80A speed control min.

EDIT.
check out the cheap esc thread. They have 100A speed controls for 28 bucks.

EDIT
I'm a big fan of my villain since the last time I took my supervee to the lake the water was to rough to get on the plane.
