ToyGuy,
I like the direction your going with the mounting board. I did the same thing on my new Lund. Here is a suggestion that I learned the hard way. When mounting the board ( I used two small scews and marine silicon), make sure you don't mount it too far down. I would leave it up 1/4" above the hull bottom or mount it level to the bottom but grind or file the the bottom of the board at about 15 to 20 degree angle so that when the boat is trying to come up on plane the bottom of the board doesn't create more surface and additional drag.
When I first mounted mine, I noticed my boat trim acted very different and the boat came on plane different ( slightly slower). I noticed a spray coming of the transducer ( normal) but also from the bottom of the board ( level) with the bottom of the hull. Once I filed a 20 degree angle on the board, every thing came back to normal. Also be careful that your transducer isn't mounted too low or in a location that one of your bunks/ rollers on your trailer align up with it or smack it while loading.
