Default 2018 spark trixx impeller\drive shaft problem

Hello, while riding my 2018 spark trixx yesterday it made some wild grinding sounds and then wouldn't go anywhere..... I thought it was the impeller so I got it home and took it apart but when I removed the impeller pump, the whole drive shaft came out with it. I'm new to the jet ski world so I'm not sure if the shaft is supposed to come out that easy? The machine only has right at 10hrs

Did somebody run over something. Yes the driveshaft comes out after the pump is removed.

Can I ask the obvious question....why didnt you take it to the dealer for warranty?

Well I thought it was just the impeller so I was going to replace it myself. My dealer would take forever to get it fixed, but with this drive shaft problem I will take it for warranty. Not sure if they'll fight me for warranty work with the impeller being chewed on a little

Your splines are trashed on the crankshaft as well as the driveshaft. The boot holds the drivesshaft in but yours is clearly torn apart from the driveshaft stripping out. Put it all back together and let the dealer take care of it because it will need the engine pulled out to replace the pto adapter.

wizzer,
I understand what you state above. What would cause the shaft splines to strip out? Lodged impeller?...and the motor won?

There are a lot of theories of why they strip out . My personal best guess is the motor was not in proper alignment from the factory . It is known that some engine mounts are found not to be installed correct from day one. That all should be checked before it gets reinstalled . I have a 2014 with a 100hours on it. Ive gone through a bunch of wear rings and plowed a lot of sand bars and my splines still look like new. If it had something go through and jam the prop to were it would strip the spline you would have some serious destruction of the wear ring and blades.

I thought the 16 and newer you didn't have to pull the motor and crank you could just replace the adapter?

Does anyone have a 2016-2018 service manual to confirm it can be removed in chassis? One would think it would be since thats how the older 2 strokes came off but they are different adapters. That would pretty much make life a whole lot easier and less expensive.
