Hey, I have a 73 glastron carlson cv-19 jet boat, it has a 455 olds motor and a berkeley jet drive. i was just given this boat but the motor will not turn over. I want to know if I can remove the motor and jet drive as one unit and if I can't does anyone know the best way to remove them. This is my first boat and am just now learning about boats in general. I do know auto mechanics and principles. thank for the help jim
