Im not sure but I believe it is EZ that is making the TM mounts
that you guys are using. Here is what I have, on this new to me boat, I put the terrova on it and the way the boat setup (where Hugh had them put the place to mount the TM) when mounting the Terrova, I was not able to use all the mounting bolts because of I couldnt get to them or if I tried I would be drilling into the side of the boat and the bolt would be sticking out of the side of the bolt on the outside. at slow speed it seems fine but when I hit the rabbit on the ipilot remote, I noticed the front of the motor reared up about a 1/2 to 1 inch, dont know just how secure that would be like it is
thanks
