prop shaft replacement

Greetings folks. I am a new (as of last Fall) C36 owner and am half crazed :eek: to get it in the water and enjoy it. I have been following this site and have found considerable very useful information I'm using to undertake deferred maintenance and preventative maintenance prior to launch - which was supposed to be this morning but delayed now because of a challenge. The issue I've encountered relates to prop shaft replacement. My shaft is out and have new shaft ready to install. Problem is, mechanic installed cutlass bearing already and shaft won't clear the rudder. I've read somewhere that with the cutlass bearing out, the shaft should clear the rudder. So, mechanic is coming back with tool to remove the bearing. My question is - assuming we can get the shaft in with bearing out, what is the method to install the bearing with the shaft in place? I will have a new bearing on hand in case we mess up the one that is in place now. love this site (below should read s/v Veritas...will correct)

Alain - If I had the choice I would remove the rudder instead. It is not that difficult to loosen the cables and remove the disc and remove a pin that is on the top of the rudder post. I recently did just that. You will have to install a new flax as well that is 3/8" square cross section - it is the rudder past stuffing box.

Alain, it is to drop the rudder, unless you have the right tool. We had to change the bearing when we bought our boat and that's how it was done. However, the C36/375IA has a loaner tool for Members that removes the bearing with shaft in place which the marina did not have. It allows replacement with the shaft and rudder in place.

Where in Kingston are you keeping your boat? We're down that way a lot, will keep an eye out for you. Glad you're enjoying the site, it is an invaluable resource to a new owner, speaking from experience.....

Thanks for the quick responses baysailor and bstreet. What I didn't mention in my post was that yesterday, I had the boat in travel lift slings with the intention of dropping the rudder to do the replacement. We (mechanic) could not release the 4 retaining bolts on the disk...no amount of effort would release them so we are soaking the nuts and bolts but are really not confident which is why I'm considering the removal of cutlass bearing and seeing if shaft will go in. So, what I'm hearing is there is a special tool specific to removing/installing a cutlass bearing with shaft in place...right? Any other advice?

Bud and Suzanne, we have been at Treasure Island Marina with our previous Douglas 32 of 26yrs for 23 yrs now and have retained our slip for Veritas. TI is on the mainland just past the western most end of Howe Island. This summer we will spend most of our time on the eastern Lake Ontario area getting acquainted with Veritas. We would look forward to meeting you and as well will keep and eye out for Delaroux. regards

Here are a few images that I am not sure where I got them from. It is easily made from water pipe.

Alain, the C36/375IA has tools which Members can borrow, one of them is the tool to remove the bearing with the shaft in.

Shaft is in....yeah!! I convinced my sceptical mechanic (he was thinking we would need to drill a hole in the rudder) to remove the existing cutlass bearing and try inserting the shaft and if successful, using the old bearing to tap in new bearing. I said humour me...let's try it. Well, it worked. With the bearing out, the shaft slid in somewhat tight against rudder but in it went. We put the new bearing on ice for 1hr hoping to 'shrink'/contract the bronze a bit. I think it did because it went in with not too serious tapping using old bearing on the end of new one, as mentioned above, along with a sleeve from mechanic's bearing removal tool once the bearing was in a bit. So.....now can schedule launch which will be early next week. What we can't figure out is why the disc retaining bolts won't loosen...some corrosion due to stainless on aluminum? Alain
