I can see the pictures, I am travelling for work right now but when I get home I will measure everything. After I tightened up some of the hose clamps there was more pressure between the SS seal and carbon seal, not a huge amount of pressure but enough I feel comfortable with, but I will still measure everything to be safe. It just didn't seem like a very good seal to me at first but if it works it works, I am not complaining. First time putting all of this back together, owned the ski for 2 years and have not really got to ride it, always had problems so I practically rebuilt the whole thing, so when I put it in the water I only have to do PM work for as long as possible. ( Hopefully )
