RESTO Impeller shaft

[Playerwho]

So interesting problem, I'm great with cars but not so much marine tech.
I've got 2 seadoos with the yellow 587. When dry starting one I noticed the shaft is spinning and turning that rubber hose over the shaft. I mean the whole shaft is spinning, grease nipple and all. Loosening the clamps on the rubber piece let's the seadoo turn over properly but tightening them is a no start because the starter can't spin everything.

The other seadoo starts just fine but the shaft doesn't spin. I have no clue what one is broken or what the normal is.

The hose and bearing assembly should be stationary. The one that is spinning has the carrier bearing seized on the shaft and it has torn the thru hull fitting out. OSD has a repair kit that includes a new bearing and they hull insert. You may need a replacement driveshaft as well depending on what kind of shape it’s in when you get it out. I’ve seen some people that had to cut them in order to get them out...

Well that's good news. They've been out of water for 11 years now so the shaft should be in decent shape still. I'll try finding that repair kit and hope for the best

If you search for “Driveline Repair Kit,” you’ll find it on the OSD site.

As for the driveshaft, you may be able to reuse it if you can get it out in one piece. I’d soak the bearing in penetrating oil for a bit and tap it with a hammer a few times to see if it will break free. If it does, just inspect and polish up the section that the bearing rides on before reinstalling it.

So the jet pump is stuck to the hull
Looks like the nozzles were siliconed on the inside and the outside has way to much silicone on it too...

Any tricks to the trade? I've read a bunch of stuff from tying the housing to something solid and pulling the trailer to using a 2x4 as a puller against the back of the hull

They can be a PITA to get off if they’re siliconed on! You can use the 2x4 method, or I use a ratchet strap hooked to the pump on one end and something immobile on the other. It’s not the safest thing in the world, but I’d rather apply tension slowly with the ratcheting mechanism rather than go full redneck and use the truck and trailer to yank it off... Make sure you use a neoprene seal when you put it back together so that it won’t be a nightmare the next time.
