AC sport 40

[RichardHart]

I'm setting up the second version of the AC sport 40 and would like some info, like starting pipe length and a good prop to start with? The boat has a N/R .46DD w/ a Macs 1345 marine pipe and 55% fuel. I will be racing in Utah so its higher up and that will affect the engine power, right? I found a lot of good info on here but most setup's seem to be closer to sea level.

Thanks,

Richard

X450, X452 b/c or 648 pipe at 10 - 10 1/4 and go from there.

I always liked an X-646/3 on the AC sport 40 I ran. Mac 45 with pipe at 10,375" 3200' elevation set up.
