The Motormate is actually an outboard motor locking system designed to protect against unnecessary harm to your motor as you haul to and coming from the water. This Motormate is actually designed to fit Mercury 2 shock 75-115hp electric motors. Depended on through several pros such as: Guy Eakers, Ott Defoe, Bryan Thrift, Randall Tharp, Aaron Martens, Timmy Horton and Jason Christie. The motor yoke space is actually the Center to Center span in between the motor connection spots getting the MotorMate to the motor drive shaft property. The transom position space is actually gauged in between the within edges of the stern braces. The MotorMate will definitely certainly not work with electric motors along with a 25 ? shaft. Please verify before buying. Get your Motormate and tow along with self-confidence.
