drive shaft bushing question

[Linwoodinmaine]

Just got my jetski running thanks to this forum thanks to everyone for the help!! I hooked it to the hose and started it then turned on the hose after a few minutes of running it kinda made howling sound so shut it off quickly. I found a video that said some bushings are made out of ceramic and you can damage them running out of water after I looked at my drive shaft and didn't know if that is where the sound may have been coming from and didn't know how to tell if I damaged it? In the pdf attached I highlighted the piece in question the boot behind it pushes back to reveal the front of the piece highlighted

The drive train area is noisy as hell out the water on the hose, perfectly normal. In the future there's not much of a need to run it on the hose more than a minute or two. Do it just enough to back flush, should be engine on for 10-20 seconds, then water on for a minute or so, then water off and clear the exhaust for another 10-20 seconds, then shut it off. Much longer than a few minutes run time out the water you can overheat the carbon seal/SS hat.

I wouldn't sweat it, you should be fine. But if you still have the oring under that SS hat, I'd switch it out to a c clip.

sorry all new to this, in front of the back rubber boot was abit warm and i can push the rubber boot back away from the piece i highlight in the pdf it looks like the or piece it is clamped to pushes away from that bushing that got warm? didn't know if that was normal? will the bushing spin with the shaft?

Like I was explaining above, it will get warm and hotter the longer you run it out the water, so limit the time doing so. The stainless piece spins with the shaft...pull it rearward to see the verify the oring or c clip. Should be some tension against the black boot/carbon seal.
