I recently acquired my fathers boat after his death. It's a mid 80's Seasport Pilot with the Volvo 125/270's. One side has a broken "U" joint in the outdrive. Having a hard time getting the hinge pins out to seperate the outdrive from the motor. One came out easy, the other I can't get out even with an air hammer. Any suggestions. The other side was done and the pins were replace with the type you can thread a bolt and slide hammer on. Any help would be great. Thanks
