J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Shaft Coupling Movement - Anybody have it?

I replaced the shaft seal (PSS Dripless Seal) this past winter and have followed the directions that suggest the bellows be compressed 3/4" by the stainless collar. I've been having problems with some significant leakage and have determined that the coupling coming out of the transmission moves fore & aft at least an inch, causing the shaft to move and water to leak in. I don't think the transmission end should move at all, and suspect there may be an issue with that. I had the clutch rebuilt 2 years ago. Can somebody check that the location of the coupling out of the transmission is fixed or movable fore & aft? Maybe use a lever and try to move the shaft. I hope I don't need to remove the tranny, but ....

I'll be racing on a C&C35 this weekend so will be off-line Friday until late Sunday. Hopefully somebody can let me know about this when I get back.

Thanks,
Bill
