Best prop for turbo rxp Scat or Solas
Would like to find out what prop works better 3 blade Scat or 4 blade Solas and a starting number for pitch.
SC 137+4 the ski runs 8950 with Solas 15/20 and 82MM ring in the nozzle. I will have my Turbo build starting next week and would like to start out with a close prop choice. TIA

I have a Skat 15/20R sitting around what do you think it will need to pitched to? Or will I need to dig deeper then I already have and buy another.

You will find a VERY small top end increase with a 4 blade but out of the hole and on hard turns it will spin out . With a skat it will hook up and go at any speed or turn.

Well the 04 rxp runs 84.5 to the best of 85.9 so I figure another 5K couldn't hurt spent some cash in the green hulk store for the turbo to support the site so it's all good. Now will it go faster? That remains to be seen there is nothing more I can do to the ski so I figure I'm done. I will post some pic's and numbers when I get it dialed in with any luck it will be ready by the end of next week.

On my turbo ski.
It was quicker and faster with the solas 15-26.5 Thanks Eric! It ran 90.5 @ 20.5-21# @8900 82mm nozzle.
it would cav. bump the limiter at 9200 then settle and fly! look down and your going 88 instantly the next couple mph took a little more time. But did not stay hooked in rough water.
The scat 3blade is a 14.5x22.5. it doesn't cav out of the hole so it bogs alittle with spooling the turbo. and the top speed is down 2mph. But it definetly hooks better in the chop. 88.5@ same boost @8800rpm same 82 nozzle.
I wish my solas was still alive, cracked tore one impeller blade.
