To ensure the MotorMate you order fits your Mercury motor, it is necessary to confirm measurements. The spacing of the contact points on the outboard motor and the edges of the stern brackets should match A and B in the chart to the right.
The motor yoke spacing is the Center-to-Center distance between the motor contact points that secure the MotorMate to the motor drive shaft housing. (“A” in chart)
The transom mount spacing is measured between the inside edges of the stern brackets. (“B” in chart)
The MotorMate will not work on motors with a 25″ shaft. Please confirm before ordering.
