Just another suggestion, you may want to look for 2 ( 95-99+?)seadoo PWC w/ 787 engines, they'll have all the pieces/parts you need, including all the screws/bolts/nuts.. Then you can sell the hull/remains or cut it up into pieces.
The 787s challengers/pwc all use the same motor/pump/driveshaft(this might be different),etc,etc. I use http://www.hlsm.com/ to match up part numbers...
