Driveshaft 2006 RXP
I was looking at my driveshaft and i was wondering if that black collar that has the black boot on it is supose to be able to move around against that stainless steel piece?

the ribbed black boot is the accordion boot. the metal piece closer towards the engine is the floating ring... the charcoal colored thing pressed against the metal floating ring and clamped inside the accordion boot is the carbon seal.
the floating ring and carbon seal are under constant spring pressure from that accordion boot....
this is what keeps ur ski from sinking... SCARY, i know

next time u put ur ski in the water... reach down there and push the acordion boot towards the rear of the ski so the carbon seal comes away from the floating ring... watch the water start spraying in... then u let go and it smushes back together and no more water...
so yes what u said is normal, i gave ya an explanation of how it all works

Believe it or not....
that is the best system for sealing a drive shaft through the
hull of a boat. The old way was to use a "stuffing box". Dating
back to steam boats it consisted of a somewhat hollow collar
stuffed with cotton or fiberglass string. You tightened it up until
if froze the shaft and then backed it off a 1/2 turn. It was normal
and expected to have that fitting leak water when ever it was
running. The trick was not too much! You carried a large special
purpose suffing box wrench so you could tighten the big nut, usually
both were made out of brass to combat salt water corrosion.
My twin inboard SeaRay almost sank on occassion when those seals
started leaking and you couldn't fix 'em at sea.
This carbon seal system is known as "dripless shaft seals" and is standard
on all the newest and best boats. As in my installation you fed the
seal a supply of water coming in from the raw water intake to keep it
running cool. I don't see that feature in the SeaDoo setup which may
be a reason some of those seals are failing, they're heating up and warping!
Shame on you hotdoggers!
For those that want to know more go to PSS, the ones I bought for my boat.
