300/440/550 JS440 impeller removal?!

[Serio]

Ok so here's the deal: My friend gave me a sweet 440 hull to make a 650 conversion ski; however, I must remove the aftermarket ss impeller. It has a 440 driveshaft on it so it DOES need the special 400/440 tool. The problem is that I cant find one anywhere! found a picture of one i a friend's Clymer manual but that's it. I checked ebay, google, several online stores, the local kawi/yami dealership, and two jet ski shops. So my question is: where can I get the tool, or how can I get this impeller off?

Thanks,
Serio

I use a 2x4 and jam it in in between the blades and the pump tunnel so the impeller can't turn. Then I use a pry bar on the coupler on the driveshaft to unscrew the driveshaft out of the impeller. has worked great for multiple times.
