My mount is pretty basic and no doubt cheesy in some peoples eyes but I like it (hey, I'm a cheesy guy!) Two pieces of PVC pipe and one T connector plus four cable ties. One PVC pipe long enough to stick out from the frame past the pontoon plus sticking out a little extra on the inside so I can fasten it. On the outside attacha PVC "T" connector. From the bottom of the "T" put a second piece of PVC long enough to extend into the water a coupleof inches. Attach the mounting bracket to it and you are good to go. I do not glue any of it which allows me to swing the puck up out ofthe water when going through heavy weeds or rocks and such.

I'll take a pic tonight or tomorrow and post it.

P.S. I position the puck sticking straight out from the pontoon. If it is under or next to the pontoon I sometimes lose bottom.
