« on: December 18, 2021, 11:28:46 AM »
Does anyone know the length of the shaft tube on the interior of the 303 Pearson?

Could someone send a picture of your shaft tube and shaft seal on a Pearson 303

I own a 31-2, so can't help you specifically, but that looks the same as my PSS dripless shaft seal for my boat.  What exactly are you in need of the measurements?  It appears you have them right in front of you, so I imagine you're wondering about something involving them that perhaps we can answer.

My question is how long is the shaft tube? I think the previous owner installed the PSS seal to far down the tube and that won't let me compress the bellows. A picture of your setup might help.

the install looks perfect from what I can see. It has to be all the way down to the stern. The compression comes from the other end and can be difficult to do....I always get something to force in-between the end of the engine coupler and seal to keep it in place while tightening the seal down. I have a Supco Belt tensioning tool I use for my alternator that works well for tightening the seal as well.  Just know that each spring, if you just put the boat in the water "without" turning the shaft a few times first, it WILL leak!!!   As for a picture of mine, the boat is 6hrs away on the hard, so can't help you there :)

Thanks for the reply. I was thinking the previous owner pushed the bellows too far down the shaft tube and  when I try to compress the collar, the carbon and bellows hits the end of the shaft tube.
