Ran great all day still working on the handling and need to get the rpm's up some. Lugs sent me a 9/19 to try and see if I can find the 300 rpm's. Today it was 7600 @ 60-61. Also today it seamed to cavitate real bad I had the CCS grate on. I will try the R@D next time.

i really like the R&D on the SLT hulls.
The final RPM's and speed are such a bitch to get but so damn easy to lose.

Make sure the pump shoe is siliconed real good. When mine was cavitating I lost some RPM. After I resealed it, no cavitation and RPM came up around 300-400.

Beer, You are going to lose huge rpm's with a 9/19. A stock dialed in 785 motor will only turn about 7900 with a 12/17...My guess is that your rpms will drop to about 7300 or so. You may want to see if you can work on your current setup to achive another 300rpms. Just my 2cents..

Sounds good... I know Mark's 785 with Moto Marine pipes and a fully ported more will spin a 9/19 at 8100. Good luck with a stock motor and stock pipes turning that impeller.
You guys should take a trip to Seaside Heights NJ next weekend. We will be there with 5 Pro's.. Mark included..
