Thought I'd post some pics of my motor build for a Hobie PA 12 with a West Marine Minn Kota 40 motor.
I used a standard Hobie plug, installed some aluminum plates for support and encountered some trial and error.
Berfore you start something like this, check the exterior diameter of any motor, the blade path and the width of your particular plug hole.
Hobie PA's have a wider hole then some of the older Revo's - this unit will not fit in my Revo.
Drilling out the support plates
Preliminary mounting
Opted to reinforce the internal of the plug with some foam - this was a treat and a learning experience
