I am finally back to finishing the (6) 48" dropped sponson hydros. Hull alone is 6 lbs. I have 10 ..2.2 amp. Dewalt cells, A Novak Super Rooster ESC that handles a car battery with a 41 # thrust trolling motor easily.
How little power will a ready to run 10 lb. boat need to run surface or submerged at 20...25... or 30 mph ?
I probably will need to buy from Hobby City in China.

Money is a big problem with 6 ESC & 6 motors. I am using the seperate Octura flex drive shaft & seperate rudder setup.
