All right...I've hauled the boat to replace thru-hulls and the cutless bearing. It sounded simple enough. HA! I cannot remove the prop shaft from the connector flange. I've soaked the area including the set screw hole with penetrating oil, heated it with a torch and put a harmonic balancer puller on the back side to pull the flange off the shaft...all to no avail. Short of cutting it off and using a hydraulic press to get the remainder out...and buying a new shaft, what else can anyone recommend. Also, any leads on where to get a good deal on a new shaft, or even a used one? Thanks.

cut it off buy a new one
Brian, Save yourself some time and sweat. Cut the shaft off at the flange, pull it ou and forget about it. Chances are the shaft is scored at the bearing or the stuffing box and you'll have to replace it anyway. I wouldn't bother with a used one unless your sure of the source. A new one will run you around $300( I know, it hurts). If you havn't already done so, install one of those dripless stuffing boxes, they're great! Good Luck

Save your $$$ and do this...
Go to the PYI web page and check out the installation instructions for their dripless seal. It deals with removing stubborn couplings. You might want to consider putting a shaft seal on while you have everything apart and never having to deal with the packing gland again. Anyway, cut and paste this link: www.pyiinc.com/index.php?section=pss_shaft_seal&action=instructions&sn=2 Also, check out sailnet.com and their email list for catalina 30 owners. We have about 350 C30 owners trading tips and tricks for these boats. If you had been on the list you would have already known how to remove these stubborn couplings

Thanks for the info
I found a new stainless shaft made to order at "www.properpitch.com" in Delaware for about $140.00. You can also get the stuffing box and replacement coupling pretty cheap. I'll probably save myself an additional 10hrs. of labor and get a new one.

Let your flange bolts work for you.
After pricing a new shaft, you will want to try to save your old one. Take the prop flange loose from the transmission flange. Put a nut in between (centered) and tighten the four bolts down evenly. Add more penetrating oil, bang with hammer, and cuss. It should start to move. Loosen the bolts up, install a larger nut (or any thing you can find that is a little thicker) and re-do the process. A little at a time, it should come out.

make a pusher
Brian I just went through the same problem last weekend and what I did was this. I found a piece of 3/8 thick plate at a scrap yard and drilled 4 holes to match the ones on the coupling. Next I drilled and tapped a hole in the center of those 4 holes (1/2 20 thread). You can then take this pc and bolt it to the coupling, screw in a bolt thru that center hole untill it seats on the shaft. Next just keep screwing that bolt in and it will push that shaft right out no problem. You can then put this little fixture in your tool box for later use, you may have to go down this road again.

Split the flange at the tranny.
Brian, It shouldn't be all that difficult. If you begin by undoing the flange itself into two pieces, you can slide the whole shaft assembly back abit towards the shaft seal. This will allow you to see the stub end of the shaft, which (with the setscrew backed out) will probably slip right out of the back half of the flange with very little coaxing. Good luck....
