Foam puck and water transducer installation

Saw this option for installing a transducer.  Just wanted to add it to the forum in addition to the foam puck method.  I am using the foam puck approach but like most of us, always looking for a better mouse trap.

The best way to install a transducer on a kayak

Don't watch that video if operating heavy machinery, may induce drowsiness.

Probably stickier than an earlier mentioned version that suggested plumbers putty.

I've found this to be the best way.  Unless you plan to put the Transducer in another boat in the future.

Lee, for real this works? Put water under it afterwards?

No water needed at all.  Stick it in the hull and forget about it.  Rav and I both use that setup.  Solid performance.

I'll be converting from the foam puck and grease mount to the plumber's putty (Duct Seal) in the near future. 

Interesting. I made my foam pucks for my Ultimate 12 and mini-drifter from 2" thick closed cell urethane foam and glued them down with Marine Goop. They have high sides, a snug fit, and haven't leaked yet in over 2 years, maybe 3.
I've been using an external custom mount on my Tarpon 140. It attaches to the stern via a special bracket I made that uses the existing screws for attaching a rudder. I have been waiting to get a better FF with gps before I do an under deck installation. I've been using the same FF on all my boats.

The Duct Seal looks pretty quick and easy. I have a bunch of the urethane foam, though, and it seems to work. I might try that Locktite epoxy plastic bonder to glue it down, instead of Marine Goop. Looks like useful stuff to have around the shop, anyway.

Lee, that glue looks pretty good, if you want a permanent fix. Thanks for the info. I assume it can be used without creating any air bubbles under the transducer.

I didn't have problems with air bubbles.  Make sure it's warm ( above 65) and put extra on, then set the puck down on one edge and push down flat.  That creates almost no space with minimal epoxy between.  I should note that I sanded both the puck and the hull prior to applying the epoxy.  It's technically not recommended for polyethylene, but I've dropped the kayak several times and bounced it all over in the surf, and the mounting held just fine.

Anyone know where you can actually purchase some of that duct seal in the PDX area?  I've been to Lowe's, Home Depot, and Ace...no beans.  Most employees keep trying to sell me the plumbers putty but it just doesn't seem like it will work the same.

I can order online, but would like to have it now.

I tried the plumbers putty from Home Depot. Pretty crappy stuff. Doesn't hold and doesn't seem to like salt water much. Or bumpy waves. I'm switching back to the puck on the new boat.

did you look through the electrical section at home depot?  That's where it should be, not in the plumbing section.

 As Lee indicated.....the electrical dept. in Home Depot.......It's made by GB...."Gardner Bender"....in a white plastic bag, 1 pound pug.
My bag has bar code # 32076 80110

Yep that's where it's at: I went back to the same Home Depot that "didn't carry it" last night and found it in the electrical department.

Thanks again Lee

Looks like Hobie is stepping up the game on Fish Finders:

Mirage Pro Angler 12, Lowrance Ready

That boat is awesome. I'm really thinking about adding a PA12 to the fleet. A lot of fun and extremely comfortable to sit in.

trying to find out if you can do this with any transducer or duz it have to be a "thru hull" transducer?? I have a 3 year old himmingbird fishfinder pretty basic
