I have a Mercury "Classic Fifty" 45 hp. Ser# OB204747. My problem is the tilt/trim motor. I removed the motor and opened it up and the brush plate is fried. Im assuming the rest of the motor is cooked as well. This is the square "Eaton" motor and it is no longer available. I can buy a used unit on Ebay but I really dont want to spend that kind of money on something that might die real soon. Does anyone know of a replacement ? What woud be my best route to go on this? Its a sweet little motor and I really to fix it.
