Giving it a try - Driveshaft Seal (no more carbon ring)
I know there's mixed opinions on this type of driveline seal, but I'm just sick of dealing with a circlip everytime i gotta take the motor out, and these days that is way more often than i like or would like to even admit.
In addition to that inconvenience, I've been chasing a slight condition of taking on water while under way, but not while sitting in the water with the machine off. Subsequently, and since my motor has been apart (again) for over a month, i took the leisure of tearing every single water line out of the ski on the "open loop" side and went inch by inch looking for a damaged hose. Then i took off all the sponsons and RE block offs and resealed everything. and as a last effort to prevent the possibility of the carbon seal losing intension, prevent cavitation, and prevent the need for any type of driveshaft removal tool ever again i sprung for the bearing carrier style driveshaft seal ("similar" to seals found on Polaris, old Seadoos pre-'96, etc)
Here's some pictures, hopefully i'll get to try it out soon, but in the meantime it gave me something to do in my desperation to tinker with my ski which was followed by its 13th waxing since the last time it touched water
maybe now i'll tinker with the open loop cooling kit i've had sitting in the box since March... the closed loop cooling is my next source of aggravation

Shib i got two (2) of those and i had to remove mine to glue in that clear plastic seal ring stiffner in so it would stay Bro! u might keep an eye on it. when it comes out of the seal end closest to the motor u can see it with the engine idling and a flash light! just thought u should know! as well i got 2 different sizes the shorter one is 5 5/8" and the longer one is 5 8/7". if you can let me know what size your drive shaft seal measures in length i would appreciate it. thanks! good luck with yours!

5 5/8" and 5 7/8" sorry typo! from boot end to end of aluminum seal where the clear plastic seal stiffner is located. thanks!

Steve... there is actually a bit of lee-way as to what the length of the rubber hose can be. So long as the seals are within, or between, two certain lips on the driveshaft it's going to seal properly. It's not an exact science, but it's a reasonably close type of science, lol...
i will measure mine tho for you tomorrow so you can rest easy about which one of yours is more common, but there's defintiely a small amount of variance that's allowed.
i'll keep an eye on that plastic stiffener, thanks for the heads up!

Shib i figured as much about the length because i seen where it rides on the shaft but was CURIOUS which one of mine is closer to yours in length. as well u can see one of mine has a bent rubber boot and has never been installed and was curious is yours bent any??? thanks! you will need to fold up the rubber flap off the rear engine drive shaft bearing when u go to view the clear seal stiffner as well because as u can see the end of the drive shaft seal rides very close to the rear engine exterior drive shaft bearing. hope yours performs and u get rid of your cavitation. im putting mine back in before this weekend and trying it again!
