After reading all the horror stories about using Marine Goop to mount a transducer, I decided to try a Wet mount setup and 4 trips later, still rocking!
Started with a lock and lock air tight plastic container.
Mount the transducer to the lid with stainless steel parts.
Now that you know where the transducer sits, cut out the bottom of the container around the transducer.
From your local hardware store, rubberized weather strip will provide a flexible base layer to attached to a non-flat kayak hull and be generous with lots of Marine Goop to ensure it's sealed to the bottom. Wait a day and begin testing.
I fill up with the water from wherever I'm fishing to start the day with accurate water temps. I use a $4 multi-use pump from Harbor Freight to get water in and out.
Works like a champ!
