07's still use ceramic washers
They're slightly thicker and are made with a new process.

I wonder if it will be worth giving it a chance, or just replace them with the steel washers instead.

When metal washers go out do they do more damage than the ceramics? I really need some answers because I'm in the middle of the debate due to the fact that someone I know had metal washer failure and it did some big time damage. Let me know, thanks!

I think we should both follow Jerry's (GreenHulk) advice on this. . . .

Even though Sea-Doo might have increased the durability of the ceramic washers, they still are ceramic meaning they can and probably will break at some point in time.
I have worked on more engines than I would care to admit with substantial damage caused by these ceramic washers. As most know, when the ceramics break they get grinded into tiny pieces that trash anything that they come in contact with. The list of ruined components include both oil pumps, oil pump housings, lower end bearings and all of the ceramic particles gets into all of the oil passages. A real PITA to clean up and fix. The entire engine has to come out of the boat and the cases have to be split.
IMO I would just get Jerry's metal washers and call it a day. You put them in once and maybe change them every 100 hours with a fresh set. This really is a no brainer as the worst thing that happens to the metal washers is that they will slip when they wear out but the ceramics WILL break.. Its not if but when..

I'm just now learning about the differences in washers so I need to know - are Jerry's different from other metal washers that are available? What about the metal washers that have failed (I know for a fact that some have failed - don't know who's they were but some have failed). Will that cause worse damage to the internals? What about the hydraulic system that PPG has developed? I don't want to have to go through the sc crap again so I'm looking into this very thouroughly. Thanks for all the help everyone!

Jag, my metal washers are different in that they are not titanium nitride coated. Everyone else's are. The coated washers tend to glaze over and slip.
Metal washers do not fail. They slip. When they slip you simply add a shim to increase the tension and you are done.
I don't know where you get your information about metal washers failing, but i have not heard of one single issue. Ask the person in what way they failed. Ask him to provide pictures. Just speculation here, but this person is probably trying to lay blame on bearing/gear failures to the use of metal washers.
Lastly, PPG did not develop the hydraulic clutch. That is a Rotax Racing item developed by Franco Dettori.

Also, being that the new 07 ceramics are thicker i will have to have yet another set of metal washers manufactured to work with the newer superchargers.
I don't care if the 07 ceramic clutch is "new and improved" there is no way i would run a ski with anything else but metal washers. Just like bttek1, i have seen way too many ceramic failures and the damage they can do.
