SuperJet Magnum Set-Back 140mm

[SS Jay]

Hey Guys,
I bought a RN SJ off a local racer, it was basically just a hull, pump and pipe, no motor. Ive decided to part it out. I wanted to put the pump on eBay unless someone here is interested and was just wondering what a fair starting price for the auction would be? It appears that the pump was recently reconditioned as it looks like new on the inside. It's definitely a set back magnum 140mm with a new skat trax impeller. I can send pics if anyones interested. Thanks in advance!
Jay

That looks like a 140mm. 98% of all mags in the day (96-03) were 140mm

There was a complete set back stator exchange 144 skat pump that sold here for 500 back in January. Someone got a hell of a deal.

How can you be %100?

A little more info, this thing was professionally reconditioned by some outfit in California. Has new bearings and impeller, I believe the driveshaft is new as well but not positive. The vein guides have no nicks or any sign of damage. This has not been used or installed since the work was done.

Measure it to verify size. If it's a 140 it might be harder to sell but I have heard you can bore them out to 142 maybe even 144

MTRHEAD, You're right. Sorry guys. I just measured the backside of the wear ring and its 140mm inside diameter.
Can I edit the title of the thread? Sorry for being a newb.

Also included is this pro-tec drop nozzle. Everything for $1000 or B/O?

The chamfer in the wear ring is the dead giveaway. Plus, @MTRHEAD knows race parts.

It's not that easy, unfortunately. The wear ring can be swapped with a 142/144 but the stator is stuck at 140mm. Using a larger wear ring would create a hard step from the ring to the stator. It's a 140mm for life.

Great to know. Thank you!

Good info there. Thanks for clearing that up.

What pitch impeller? What year RN did it come out of?

 

[SS Jay]

Sorry, don't know the pitch. Came out of a 96 hull.

 

[Vortex]

I would guess it's about a 14/20 pitch if it had a 771 super stock/mod motor, slightly less pitch if it were a limited ski

 

[MTRHEAD]

Sorry, don't know the pitch. Came out of a 96 hull.

got a picture of the boat? Might be one of my old race boats, If not I know I made that nozzle.

Shot in the dark, looking for this pump setup if anyone has one. Want to build an old school pre 08’ RN buoy chaser

im interested in what you end up getting for it. I have the same pump, and could be persuaded to sell it as well.
