Foam puck and water transducer installation

Most any transducer works, doesn't have to be a thru hull model. 

thats great, after posting my question I actually found the manual onlimne and its going to work out good. just got my trist seal 6inch cap and some marine goop, just need to carve out some foam and cut some holes and Im ready to go!!!

here is my installation:

I have done two fishfinder installs using the duct seal method, now, and both times it has been extremely easy and quick. My first install was the foam method on my Cobra Fish and Dive, and it never really worked well. I blame myself mostly for lacking patience. Either way, I will not ever go back to the foam puck, unless for some reason the duct seal doesn't work out long term. Definitely get the duct seal and not plumbers putty.

Keep us up to date with any issues.  I've tried a number of in-the-hull mounts for my Humminbird transom transducer including Duct Seal, and have gone back to a foam puck and water. However, I do not know whether my transducer failure was due to the Duct Seal or not.

If you have not seen the existing thread(s) search "Duct Seal" under "Drillin' & Cuttin" with me as the user.

One other detail regarding the foam puck method. I only use fresh water to fill the puck.  As mentioned above I carry a large syringe (25ml) sans the needle and use it to suck water from my water bottle to fill the foam puck.  This keeps the puck and transducer clean.

I searched online for the best Glue and read that Gorilla Glue was the best for just about anything. Goop was rated #2. So I decided to try Gorilla Glue to mount my foam puck in the TI. Gorilla Glue is supposed to be water activated so I dampened both the hull and puck then applied the glue to the puck and pressed it onto the hull. Let it cure overnight and was very disappointed to see the glue stuck only to the puck and came off in one piece from the hull leaving not a trace. Guess I'll try again with Goop in my Trident 12.

On the bright side, this motivated me to create an external transducer mount for my Elite5 DSI. That came out awesome, will post up some pics separately. 

Rough up the spot where you're going to stick it with a little sandpaper maybe.

Duh, thanks for the tip, I definitely will do that before next try.

Thank you for the advice! Worked like a charm!

Outfitting your kayak is like sex, only better! Kidding! Kidding! Sex is still better.

This is not a puck, so technically it is an off-topic, but it is still a transducer installation.

I know that it may not work for a lot of folks, but it is OK with me as I don't use Hobie cart. Holes still can drain water. The reason why I decided to give a try to another approach is because hull plastic absorbs too much of transducer power and a 1200 ft transducer don't see bottom after 500ft. I also added water speed gauge as it seems to be very important for trolling.

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?
