hey guys, need some help with plane out. i have a mercury 78 90hp ob, with original prop, i have put this motor on a longer size boat and also heavier, i need to make a prop change to plane the boat out faster seems that its taking too much strain on the motor to plane the bigger boat. what are my specs on the original prop and what do i need to change it out with? thanks joe p.s. the original boat was a 16ft and now its on a 21ft
