Thread: What pitch??
06-25-2006, 01:42 PM #1
What pitch would I be looking for when my boat (basically has a riva stage 2 kit) is turning around 7,060-7,080 range with a 13/19 setback Solas on the old style pump?
I'm still trying to understand the whole variable pitch impeller thing.

You're in the right rpm range now, what are you looking to do switch to the 05' pump?

I have a 05 pump...but, it has a SCAT 15/21 prop...it's to much for my current mods. I'm either going to sell it and buy a new 14/20 or send it to Speedfreaks or Impros and have it repitched. What to you think my RPM's would be at with the 14/20 on the 05 pump? I want to make sure they stay above 7000.

i would venture to say that you need to be looking for 7150-7200. You could have that scat prop depitched to a true 14/21 (from a 15/21 like you have now). You probably wouldn't need much because your rpms are really close to target--but just a hair shy.
I guess it's better to have a little more than a little less. Just my 2 cents.

So, you think if it gets pitched to 14/21 my rpms will come up some to around 7,150 or so? Once I get my prop removal tool from Riva..it's going to come off and get sent off to impros or speedfreaks for repitch. I want to do this once if I can and get my rpms where they should be.
P.S. I'm still working on the banner for MB-3....
