Problems with carbon seal leaking-- possibly this instead...

[VFX_Artist]

alright this has been a headache for me -- a few months ago i sank my ski and thought it was the carbon seal itself... after many trips down to RIVA and with help from Frazier at PPG we figured out that this little black piece of plastic had come off the end of my driveshaft after one of my many prop changeouts... with that part gone it allows ur driveshaft to move back forth, letting the carbon seal allow water in... well its been working great for many trips out now.. till the ohter day.. was running great then all the suddent the same things happened like before.. No acceleration at all... looked under the seat and was spritzing water from the seal ......took the driveshaft out to see if the piece was still there and yep it was BUT this time it MELTED ..here's a pic... luckily its only like a $5 part... i'm just glad i'm not paying almost $2k again to figure out this problem....

the boot should have enough spring load to make up for the small plastic spacer. You boot may have never been loaded properly after all the changes.

how big is the spacer?

Just keep an eye on your engine mounts, also when re-installing that shaft make sure the tell tail ring on the drive shaft is all the way in.

Check your motor alignment!

or get the Rotax driveshaft seal with the grease fitting...And ditch the carbon seal altogether

I think he did that. This thread is like a year so old....

that little plastic cap, that on the engine side?? not in the impeller right? I have my pump out, I'm scared after reading this post, I dont want my ski to sink! Why would the impeller loosening up cause the ski to fill with water?? wouldn't the shaft still spin?? the only area for water to come in is that carbon seal.. ??

The old seadoo's had the cap but I am sure the RXP doesn't.
I will double check.

The RXP has the cap. It's on the engine side.

I only see one on the motor end
