Foam puck and water transducer installation

Are you worried about banging up the transducer having it hanging it out the bottom like that.  What happens when you drag your yak onto a beach?

Nah... Not really worried. Outback has quite deep "keel" and both transducer and speed gauge are "hiding" good enough. I will take a picture from a side once I will get home.

Actually I was just partially correct. Transducer is OK, but speed gauge touches sand during beaching and actually shows some wear. Interesting thing that speed gauge has to be fully submersed, so there is no way to make a puke for it.

I don't know how long this thru-the-hull transducer has been around, but I just saw it.  If you have $97.43 you want to lay out you can get one from Amazon: http://www.amazon.com/gp/product/B000G6633Q/ref=pe_225870_112512140_em_1p_0_ti



Seems this would be the best solution but just a little pricey for me.  I'm currently using the duct-seal-well method.  It seems to be working okay, but I just wonder about the effect of shooting through the hull.  My friend's in-the-water transducer signals more fish.  He said mine was too cheap, Humminbird 153, at about $80, and wouldn't detect as many fish .  He didn't catch any in his powerboat nor did I in my Hobie Revolution, so....

The way I did it, was to cut about a 4" long piece of 4" pvc, used duct seal (purchased on ebay or amazon) to attach the pvc to the inside of the hull, just behind the mast post of my Hobie. I just plop my transducer in the pvc well, which I then fill with water from a water bottle. I have never had a single issue with this setup, no bubbles, nothing.

Jerry, someone did a comparison of thru-hull vs. open transducer efficiency a while back.  Might want to try a search for it, but as I recall, there's a negligible difference between the two for clarity, depth, and detail.

If you want a slightly more permanent solution you can take electrical putty, roll it into tight ball, and press the transducer into the ball against the hull. I've done this with multiple kayaks as long as you get the air out of the ball it works great.

I like that idea, and might give it a try, but I also kind of like being able to more easily move or remove the transducer. I've always tended to strip almost all accessories off my boat for travel and storage. I'm sure it's not necessary...

I've always kept the transducer attached to the kayak. The putty will keep it attached for years without issue, but if you wanted to remove it you can just pull it off with a little bit of force.

Yeah, that putty is good stuff. Lots of uses. I probably will end up ditching the pvc and just do putty. Thanks for the input!
