I`m replacing the carbon seal/carrier seal.Noticed my 97 challenger[single]doesn`t have a thru hull fitting like the one sbt sells.Mine appears to be a black peice of pvc running thru that boot clamp on.Is that normal or do I order the one pictured and seal it in?Pvc has a large dia. doesn`t seem to me that it needs to be that big of inner dia,for cav. purposes.

I think its ok to Doc.,the carbon ring was dragging on shaft,almost made a horse shoe out of it.Yesterday we went way south on the lake.Turned to go back and instant cav. thought the splines spun. I just removed pto no signs of bad splines on any of contact areas[removed pto with impel. tool]I hadn`t got to the carbon seal yet this is our 3rd season with boat,just didn`t leak.Shaft has a little rub but not in carrier area.That thru hull might have been repaired by Karl the guy I bought boat from across lake.Clean repair just different then I thought it would be,if not original. Thanks
repeating misaligned carbon seal/carrier
Made it to lake with new driveline kit installed,never ran better.The driveshaft was quit,before the carbon seal was rubbing on it and noisy.THAT WAS until I was ready to leave cranked the boat around to load.That same noise had returned got it home and carbonseal/carrier face was misaligned like before.Now I had the new boot compressed all the way back to the third notch[rubber ring in 3rd groove[aft] on shaft]and the boot is flush at rear to fiberglass over thru hull. Thru-hull is black pvc and looks like the shaft protecter had been removed on pumpside. I thought about repositioning the accordian boot and pull bottom side out a notch to compensate for shaft angle going to pto,then retighten clamp,has about 1.5 inches of thruhull sticking out to play with.Or replace thru hull or go retro?:blush:

reposition
Thats what I'd do. The Factory may not have installed the thru-hull properly.
Just keep the seal from rubbing the shaft.
