First off, I'm running a 656 Ambush elite, 2007 Yamaha 2 stroke 50 with a 15p quicksilver prop thats been dinged up and then worked back smooth. Vance kick plate and jack plate, cav plate about 1.75 inches above the bottom of the boat when level. Two batteries and gas tank in the back. Was running 5200 rpms with a 16p Quicksilver prop, not sure with the 15p because the tach finally gave out today. I'm at 41/42 mph before it starts bouncing too much, and if I trim a bit more, itll start to blow out. I can run 39 easy with no bounce, and 36 before I hit the trim at all. Have I pulled about all the speed I can out of the boat, or is there a decent bit left? It jumps on plane well now, and if trimmed down still turns without blowing out. Should I try a 14p next? Will the drop in pitch but increase in rpms keep me at the same place? Am I wasting my time chasing the next mph or two? The boat only ran 33 with a Powertech SCB 15 when I got it, so I've enjoyed playing with the set up, but now I'm not quite sure where to quit. Anyone running a similar set up? What speed if so?
