Re: What are these controls from originally?
You have a Morse Control. As suggested by the previous replies, it will fit just about any motor if you are able to get the proper cable ends to adapt the motor ends. Also, the control itself can be set up for various motors. Some pull the throttle to open, some push to open, etc.
Morse Controls company was sold to Teleflex. They (iboats) should have new cables, but good luck finding adapters for some of the odd-ball motors.
