What happens when you pull the pump and the driveshaft comes with it?

So I had to pull the pump to replace the plastic nut that broke on my reverse cable. In the midst of pulling the pump, the driveshaft decided to come along with it. I replaced everything and had my son guide the shaft back into the PTO and everything seemed to meet back up. I started the jetski and the prop turned, so I thought I was good. So the other day I propped the skis up to keep the rain off of them and noticed an oil spot in my driveway. I looked closer and it looks like oil is leaking down the driveshaft. I am pretty sure it is coming from the oil seal at the back of the PTO (don't know what it is called), but I wanted to ask the gurus on here. If it is that seal, and I have to pull everything again, is it worth it to change the carbon seal. Ski is a 2008 Wake 215.

Thanks in advance.

There is no way the driveshaft could come out unless you uncoupled the carbon ring assembly which would have been unnecessary for pump removal , in any case when the shaft came out you may have pulled the seal bearing out of the bellows at the end of the engine , its held into the bellows with a clamp , sometimes you can push it back in and using a special pliers tighten it up , otherwise I use a special narrow band gear clamp (2 put together) to seal it back up. Look for tears or failures in that boot , another failure issue.
 
After looking at parts and names, I think it was the output shaft which decoupled from whatever it connects to. There was a small rubber seal on the shaft, which I think did not seal right. I am going to order one and pull the whole thing apart again. I just wasn't sure if this could cause an oil leak.
 
Update: So I pulled everything apart again and Digdog was absolutely right, that output shaft is not going anywhere. After looking everything over, the pump is what is leaking. Does anyone have any ideas on common leak points in the pump? The oil dripping out is dark gray was leaking onto the wear ring. it only leaks when the pump is vertical. Any ideas?

Thanks
 
The pump bearing is lubricated with either oil or grease depending on the year and model. Download a service manual, it should be serviced every couple of years anyway.
 
So I pulled the nozzle part off of the pump and removed the cone, which was not leaking. I am assuming this means the leak is on the front side, which means I have to pull the impeller and replace the seal on the front side. Interestingly, the oil was in the wear ring and only leaked when the ski was tipped up, which is perplexing given the front seal is the one that is likely leaking. Is it worth replacing the bearing and everything else while I am in there? Also, the boot on the impeller is worn down and parts of the plastic are wearing off. Does this part thread on because it isn't budging. Do most of you just cut it to release the threads? I am getting closer to realizing that I am going to slowly rebuild this whole jetski.

Your pump is not supposed to have any oil in it. It only has grease which does not leak oil. If it is actually oil leaking, then somebody who didn't know what they are doing put oil in your pump.

The plastic/rubber boot on the front of the impeller has left handed threads and needs replaced because it is destroyed and half gone.

You just saved me a bunch of time and money. I was about to buy a bearing, the tools to remove and install it, and all the seals. Now all I need is some grease, a couple o-rings and a impeller boot. I love this forum.
 
There should be no play at all in the bearings , if no water got in then there's a good chance they are still good. I think some of the older models had oil in the bearings , not sure. Use an oem boot , use loctite on the threads if you don't have the proper boot sealant , clean the splines and add new grease there also. Use the oem grease , You have to get an ounce in the bearing and then fill the cup before you put it back on, Looks like your wear ring is toast , impeller not so good either. Good luck.

Thanks for information. I ended up going to the local shop and getting all the OEM parts. I packed as much grease as I could in the one side of the bearing, filled the cup, and put it all back together. That prop and wear ring will get replaced at the end of the summer when I winterize. Probably go with a Solas at that point and rebuild the whole pump, bearing and all. I still kick myself for buying older jetskis to "save some money." That only works if you really know what you are doing, and I don't.....yet. The old saying is true, "You either earn a lot, or learn a lot."
