So....Ive got myself another project. Oh and what a cluster bleep it is. LOL
This machine was owned by George Grabowski of High Performance Tuning. He bought it new from Rossier in 96. Doing some research I have surmised that he was one smart guy...and also one of the original know it alls (AKA Dbag...lol). I read a bunch posts on alt.rec.jetski newsgroups and he was quite abrasive and was not afraid to talk smack. So much so, another shop ended up suing him for defamation. He died on 12/12/12.


I picked this up near Detroit on my way to the LaGrange get together. I have since tore into it and taken it all the way apart. My plan right now is to put it back together very close to the way he built it and try it out for the summer. I was hoping to drop the motor right back in but one of the pistons has detonation around the edge pretty bad, almost down to the ring in some spots.
Old George was a porting guy and he went nuts on everything. I have not torn down the motor but the intake ports are butterflied as well as the intake. On one of the notes he has some scribble about porting the VE cylinders too.


There are all sorts of weird crap done to this that have me scratching my head. First off...the carb orientation and the way they open is something I have never seen before. The butterflies open towards the center

The fuel pump had an "equalizer" bar in it.

The hull is like swiss cheese..."air vents" in everything...



The hull was absolutely disgusting so everything came out to get it cleaned up. I have since washed it and it came out OK...still alot of staining. For a guy that used 8000 zipties, he didnt keep anything real neat and tidy. The power wire on the EGT gauge had 3 splices in it, the ground was just wrapped around a engine bolt. So many different types of hose for fuel and oil...just a mess. Called in the Vin number and it needs a new tank.
So anyways....gotta deal with the engine. Gotta get the top end off and hope to god things are workable. Ill peek at the bottom end and the mag housing to make sure things look decent.
Only upgrades Im going to do is go to a 5/16" fuel pickup, new few lines, new water lines, WSPS exhaust hose, MSD enhancer and Water inj controller, and I might toss on my pump off the black boat for testing. It previously had a stock SPX prop custom bent, JD venturi nozzle, and a custom made steering nozzle. Run it, see what I think, then maybe drop it in a non swiss cheesed hull with some novis and a R&D intake. Im actually looking for ideas, I cant decide what is best.
