Marc 28 AD just will not break loose. Made a puller out of 3/16 copper rod. Not sure though if the wings the right size to fit into the groove. Need to know the right size. I tried to get tool but no luck. I used a lot of pen oil and tried all day, cutting the wings down several times to get into the right grove. Having no cutaway to see where to insert wings makes it tough. This is the last phase of my restoration before I order new parts to start the reassembly. Clams says to FLMD it what's that! You can tell this is my first effort on an outboard.
