    So we installed a brand new seadoo ride plate, and an OPAS block off kit while we were at it, and the ride plate fixed the overheating issue. Rode it pretty hard for 2+ hrs and had no rpm fade or loss of speed. But it still is only hitting 7620 rpm and 62.5 on GPS. I noticed a suttle "rattling " noise when riding it which I believe is going to be the pump bearing which I hope will account for the last few hundred rpm I've been looking for. When we did the prop swap a while back I noticed the collar was loose and slid up on the shaft I guess it had been like this for some time and allowed water intrusion into the pump bearings. Boy, this thing has been an odyssey in 4-tec repair, but hopefully after the pump bearing replacement we are going to finally get to ride it more than we have been working on it.

    The supercharger slip could also be low, causing it to not build full boost. Might want to check into that. They can loose some tension after they break in after the rebuild. Do you know if OEM parts were used in the rebuild? If they were aftermarket I would definitely keep a close eye on it.

    While we rebuilt the pump we went ahead and pulled the supercharger and checked the slip. It was an SBT rebuild kit. It was slipping at 45 after break in, we re-torqued it and the little thin wrench they sent with the kit shattered like glass and flew to pieces as we torqued it so I wasn't able to get it as tight as I wanted to. It slips now at 105 so I'm hoping this is going to be good enough. We're going to try it this weekend.

    Back to the drawing board, ran it this past weekend and it was maxing out at 7700rpm and 65mph. Also added free flow exhaust since last test. Wish I could find these last 300-400rpm.

    Before I did anything else I would have that charger built with oem parts. RR

    I was thinking about shimming the SC to try to get the to get the slip higher, I've read some threads on the subject, any thoughts? Can I add some more of the old spring washers to shim?
