If the port side is as complete and original looking as the starboard side, and it turns over, I wouldn’t hesitate to pay $300 for the Cruiser, as it is. And I would feel like I got a real deal on it, too. Unfortunately, I live on Cape Cod; so that rules ME out. To me, the Mark 20 (the motor on the left) might be worth $100-$150, if it turns over. Both motors would probably need very extensive work to be reliable runners.
Long live American manufacturing!
