'96 XP Driveshaft parts missing?

[dperkinstx]

I just removed the driveshaft from my '96 XP. I'm using the parts diagram on SeaDoo Parts Nation website to see what I have.

The O-ring that goes in the groove on the shaft isn't there.
I can't tell what the metal piece is - is that the carbon ring, support ring, or both? Mine has a grease fitting but the parts schematic doesn't show any such fitting. What type of grease goes in there? Is wheel bearing grease OK to use?
So far I've only found one o-ring (part #2). It came from the left side of the metal piece in my picture.

I see an ebay ad that has all these pieces packaged together. This ad uses a "c" ring instead of the o-ring that goes on the driveshaft. Is that OK?

The picture you post is not for a carbon setup, but for a carrier bearing setup. Someone may have change from a carbon setup to the carrier bearing setup. I use Marine grade grease when I grease those fittings. You want to keep them greased or else the bearing will seize and then you will have bigger problem when it rips out the thru the hull fitting and you ski or boat will sink.

Do people switch from carbon setup to carrier bearing setup often? What are the advantage/disadvantage of each type?

I looked for a carrier bearing on ebay. I see some that look like mine but none say they fit my '96 XP.

If I buy the parts in the link I attached in my original post, will I have any trouble?

May want to get some rubber bumpers for the shaft while your at it

That's because your 96 came with a carbon setup. Advantage is that it doesn't leak water if it is maintain.

Disadvantage is that if you dont grease the bearing and it siezes, its going to rip a giant hole in your seadoo and you will sink

I bought those also.

Advantage of what? Carbon ring or carrier bearing?

There's a groove on the driveshaft that holds an o-ring. I didn't have one. Does the carrier bearing not need that o-ring?

If this was your '96 XP and you were going to buy new parts for the driveshaft, which would you purchase? Carbon ring or carrier bearing?

The carrier bearings came on older models and were replaced in '96 with the carbon ring. Logic would suggest the carbon ring would be an improved design since it replaced the carrier bearing. Of course, not everything that came on new models turned out to work better than the part it replaced.

Carrier bearing has two seals at both ends so unless the seals are worn, they should keep the water out. But you need to grease them.

Carbon seal don't have bearings so there is very little chance of them seizing up and ripping out the thru the hull fitting, but they are more prone to leaks.

You will have to buy a new driveshaft if you want to switch back to carbon seal.

My driveshaft has the groove that's supposed to hold an o-ring. That tells me I have the driveshaft that's meant to have the carbon ring. Am I wrong about that? Could the previous owner have replaced the carbon ring with the carrier bearing without replacing the driveshaft?

 

[dperkinstx]

I looked up a '95 driveshaft. It doesn't have that groove. I've concluded the previous owner replaced the carbon ring with a carrier bearing. I just need to know if that's OK, especially since UpAllNight stated I'd have to switch driveshafts.

After doing research, I've concluded I'd like to stay with the carrier bearing. I just need to know if having that groove in the shaft will allow it to leak.

Any input would be greatly appreciated.

If you keep the carrier bearing you should change the bellows out--it's not supposed to be a bellows but a harder piece of rubber similar to a cars radiator hose. Like in the below pic. I just can't see that bellows taking the torque too long before it rips and floods your hull. You can possibly cut the overall length of the new hose so the carrier seal doesn't touch the groove, but make sure the rear seal is on the shaft too. Just assemble everything less the new hose, take a measurement and then cut the OAL to that dimension. I've heard guys fill teh groove with JB Weld and then sand it smooth.

I just read your '96 XP Clapped Out thread. Very nice work.

I didn't see where you addressed the driveshaft seal. Did you go with the carrier bearing shown above? If so, what did you do about the groove in the driveshaft? I would think the rear seal is the one that keeps the water out of the ski, so maybe the groove on the driveshaft may not be an issue.

Thanks. Nope, I run the carbon seal on the xp and on my hx. Never had the need to swap, never cavitates or leaks water. The one on my 96 was on there when I bought it, it's probably original, I don't remember changing anything. I did rebuild the one on my hx with osdparts HD carbon seal kit and a new oem bellow. Now the 95 limited I'm doing came with the carrier style and I'll keep that ski that way.
