Now that's the spirit of innovation. Two days in the shop gets you out of a lot of honey-dos.

I like the idea of the well being clear so you can check the water level. The last time I went out, my Humminbird Matrix 12 started acting up. I ended up having to shimmy up to the bow, pull out my trusty Swiss Army Knife and pop the top off of my unit made of ABS to make sure that it was still full of water. (It was.) Having a well made of some clear material would have made that step unnecessary. I wonder if there is a source for clear plastic pipe in 3 or 4 inch diameters?

A couple observations. It has been a while since I worked with Lexan but if memory serves, this material can be easily welded using acetone. Assuming the weld works, (you could goop the corners as well), that would eliminate the need for all the metal braces. Of course then the thing would not look as cool.

Also, I like the portability that being able to detach the transducer from the well using a rubber cap provides. Does your design offer a way to do this?

Finally, I do believe that the Lowrance transducer can be made to fit into a 4" piece of ABS pipe. The 3" one that works for Humminbird is too small. Cali Hookup and I collaborated on a version of my design to fit his Lowrance unit. We got it to work although it just barely fit.

Nice work Doug.

I use a factory wet mount from Garmin. It recommends using mineral oil in the well but I use fresh water and it works fine. I've considered putting saltwater in to see if I get better readings but never got around to it. I get good readings to about 700 ft. I remove the heavy transducer when transporting the yak upside down. This model allows you to install on a surface not level to the bottom and then adjust the transducer so that it is level.

Garmin - Garmin 200/50KHz, 12/45deg, Plastic, Adj. In-hull Mount Transducer 010-10327-00

Installed 2006, still no leaks.


I was sloppy with the 3M 5200, but the bottom of the well is clean so that it is only shooting through water and the yak's plastic.

I didn't know about the acetone. See; you learn something new everyday. It might have looked a little better without all the angle; however, if my childhood hobby of making plastic models taught me anything, it is that I suck at making models. I always ended up with model glue all over the seams and fingerprints permanently etched everywhere. The Lexan box would probably have looked no better than the Monogram 1/48th scale B-17 that I F'd up when I was in seventh grade.

Quickly detach the transducer......no. This baby is about as permanent as the top three floors of the Sunroad building in Kearny Mesa. If I have to move it I'm going to need a pry bar and some explosives.

I think I might have been able to get the transducer in the 4" coupler if I had really tried. I gave up on it because I thought it would be too much work. Instead, I spent two days working on this. THINKING.....now there's my problem.

I'm going to scrap this thing if it doesn't give me perfect performance the first time out. I'll just go back to the tried and true Goop. I would love to get one of those through-hull transducers, but all of the ones that work with my FF are ungodly expensive. If they didn't cost $800, I would just get a bronze thru-hull with a fairing.
