Im currently running a 2 bladed 12x10 prop on a stock 31 GT (no reverse) mounted on a 1648 alumacraft. I'm wanting a secondary prop to run clean water and use as a spare. Without any mods, can my motor run a three blade? Not really concerned with speed as long as I can get on plane. My shallow running is hard bottom with scattered pads and widgeon grass. Or should I just get another 2 blade? I hear a three blade is more balanced and doesnt generate as much vibration, which would be better for running the river. This is my only boat and it will be used for everything.

I'd think you'd probably be ok wih the 10p
