I've figured out my gears now, im going with the 15%'s but now i was wondering about my prop. I have been running the one that came on it, which is a 11 1/4 x 16 hydo three blade i have tryed a few other loaner two blades, but always with the wrong gears. I am wondering what it would do if i put the same prop on but went to a hydro two blade ? ? One guy local told me that a three blade has 1/3 more lift which with my low hp engine (400hp) thats what i need. Is this in your guys opinion, or would you want to make a stab at which prop to run. Oh and by the way i dont have the ones i tried before or remember what they were. Thanks for any input.
