Thanks for your replies Larry. I'm lost on propping this thing. Trying to figure out how to prop for more rpm AND speed at the same time is confusing the heck out of me. I don't need to go faster but it seems it should. Normally, I'd be willing to give up a few mph for better holeshot but not when I'm only getting 55 mph. I'm sure not wanting to give up holeshot for speed right now and my limited knowledge of this crap is telling me I'm stuck right where I'm at.

I pulled my prop and it's a 14 3/4" x 23 pitch (3 blade) Suzuki Thunder. Found a brand new 25 pitch but thats going to drop my rpm and I need to gain 400 there, not lose it. So, a 21 would do that for me but then I'll be going even slower.
