Mine used one 1/4" bolt through flange landing on woodruff key, and two additional 5/16" bolts on flange landing directly on prop shaft. I use PB Blaster on each of the bolts, and carefully backed them out slowly (SS bolts, steel one piece flange), which worked well after waiting a day or so after applying PB Blaster. One loose, the flange rotated without much trouble, but I didn't remove entirely due to clearance issues, so I aborted my plan of removing the transmission. Cleaned up threads on flange and bolts with tap & die and re-installed with nickel anti-seize. PB Blaster is my top choice for penetrant, having used it successfully on many very stuck fasteners over the years. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto
