A nicer option if it works with your unit is this one:

They are pretty rare. Look for XFM-9-20-P

2 inch shaft diameter. 3 inch puck diameter and it only sticks out less then a 1/4 inch under the hull. Dual frequency 200/83 and 20 and 60 degree beams.

You have to cut a hole in your kayak just like with a bait pump intake thru-hull but the performance would be great and you don't have to worry about it snagging anything launching or landing.

I am planning on going through a scupper hole. It looks like it will be about an inch off the bottom of the boat, but with the natural rocker of the bottom from the center line to the sides, the transducer might not hit the bottom. I'll have to see when it comes in. The tracking lines of the boat are recessed a little, so I'll have to see how everything lines up. If it doesn't fit or look right, I'll switch back to mounting it inside with goop.

I'm not big on any holes below the water line, both for my own and what it would probably do to the resell value so that other transducer really isn't an option for me.

Here's what I came up with from Humminbird. The thru-scupper transducer was a free replacement when I bought my new PiranahMax 220. This way I get the better readings but I don't have to go through the bottom of the kayak. Hopefully it doesn't affect the glide too much.

Its a pretty clean look with no holes drilled!
