Blaster gp800 66e 120hp motor in a Blaster Illinois

[vshockey10]

I have another Yamaha power valve motor going into a ski. This one is going into a blaster. Motor is from Pat, WB800BLASTER. I can't thank him enough for all the help on this one. The main reason I am posting this is last piece to the puzzle, an impeller to match the motor. So please feel free to offer opinions up here or if you have one that will work pm me please.

Here are some specs on the build

-66e bottom end ported by WDK
-1300 PV cylinders ported by TJ
-Riva cast heads 91 octane safe
-motor mounted upright
-Boyseen reeds machined flat for upright intake manifold
-Novi 46 carbs
-pipe is a combination of the WDK manifold and gp760 dry pipe chamber
-gp760 waterbox, modded w/ 4 1" holes
-Riva out the back rear exit
-jet dynamics top loader
-long and short version JD rideplates for testing
-stock pump
-stock nozzles


Trying to set up a buoy boat not a surf boat also

simple pic for now from when the garage was a mess and even the SJ wasn't running. I will add more pictures if people want to see them. The hull is pretty beat up though

Nice set up. I'm going to do this similar set up in my Blaster
