Name This Impeller: No markings :)

Took apart the pump on the blaster today, trying to figure out which prop my ski has. It's a WB1 with some goodies all around. I bought the ski built, and was wondering which impeller it is. I thought it might be stock, but apparently stock was stamped differently. The only markings on the impeller is a 39 right at the base. Pics:

If its stamped 39 it's likely a 13/19 (I would assume). Looks like an old SkatTrak.

looks like a stock prop to me. i think stock blaster pitch is 13/18 or 13/19 anyway. they came with stainless impellers.

Yep, I think it's stock blaster too. The blades look too thick to be an old Skat Trak.

That's excellent news.... I'm looking to pick up some punch by installing a 13/17 surf prop. I too thought it was a skat trak, but they usually have markings and their logo. On the other hand, that impeller is one of the ones in better shape. Even the wear ring looks great!

Thanks again,
Dylan

ive got a c75 12/17 freeride skat prop in my blaster along with a TBM pump hub and it hooks up pretty well.

I think the ski I bought is an old buoy racing ski.... You can see the outline of a number plate on the side (where it used to be), and has a ton of good mods plus an IJSRA or whatever number on the back. Currently it's dual carbed and has okay bottom end, and is fairly quick up top. But I really want to reverse that, since I see no thrill in speed on that ski. I'm thinking about swapping back to a single carb setup for better throttle response in the surf.
