Cutlass Replacement
Hello Steve,
I replaced the cutlass this winter and ended up removing the prop drive shaft from the engine coupler and sliding it out with prop attached. First Id recommend loosening the stuffing box, Next undo the set bolt on the flange that the shaft slides into (the shaft is keyed into the flange). Next the method to remove the shaft is up to you, I sprayed with penetrant and pounded the shaft out using a block of wood and a 5lb sledge on the backside of the prop, working around in a circle with my brother in the bilge to see if we were making progress instead of beating the prop to death. I left the two flanges bolted together so only the shaft slid out.
After the shaft was out, I used a hacksaw blade as suggested above to cut the old cutlass sleeve in two places, then used a flathead screwdriver to "peel" out the brass. There is no set screw. It is a friction fit. The new bearing I ordered from deep blue yacht supply... it is a johnson (duramax) brass APEX which is what they call the 7/8" diameter shaft and 1 3/8" outer diameter sleeve cutlass bearing. I used a block and the same 5 lb sledge to set the new bearing in place as well. The bearing is slightly longer than the strut so you cut the extra off once in place if so desired. After all this, I replaced the 1 5/8" stuffing box hose with the wire reinforced exhaust type, double clamped and also replaced the (if i remember correctly) 1/4" flax packing with ptfe. You can get three rings of packing in there after pulling out the old. You shouldnt have to realign the engine after this procedure but it is always a good idea to anyways in terms of longevity. And afterall once you are crammed in that little space you might as well...  Let me know if you have any other questions, I have rebuilt this entire boat bulkheads and all over the winter and am getting ready to repaint the hull. Ill double check on the driveshaft flax size. I do know that the rudder post stuffing box uses 5/16" which i replaced last week. Everything on my boat was original so I opted to rebuild, replace or repack each item and well I guess I got a little carried away as usual... (fortunately Im not married yet...) Stick around, ive found that sailnet is a great place. Best of luck with your boat.

Reason: Remembered stuffing box hose was 1 5/8 not 1 1/2
