If you get a 13/19 concord by itself maybe 1 mph, but with an R&D or Riva plate and a R&D 800 grate you will gain about 4 mph over stock. Then if you get the J-plate you will gain 5 -6 over stock.
So 13/19 alone should be 64 -65 mph
grate plate and impeller 67 - 68
J-plate, impeller, 800 grate 68 -69
You will need to step your sponsons with the plate.
Those are results I see with my skis at sea level
If you are going to mo your engine at all get a depitched speedcut 14/20
these are all concorde impellers I'm talking about.
A Nu-Jet 6.5 is a good impeller for a slightly modded engine as well.
Hope this helps

I have a concord 13/19 if you want to buy it. I'll have to dig it out, it's like brand new

I got my plate from jim and a grate on the way just need a prop for my 02 and i should be right for a bit.

NuJet from Carl is the way to go for your mod level. Best mid and top end of any prop out there - up to about 72 mph.

the prop I have is actually a SetBack 13/20 but I'll take 140

Well hook a brother up, Carl! I'm always looking to try something new. Is that prop based on the 6.5?

I have an Island racing Nu-jet 6.5 setback, depitched to 12/18.5 with Carls race finish. It's in excellent condition and I will sell it for $150 if you're interested.
