Need help mounting transducer

[J3FFro]

Hi all,

I recently purchased a Piranhamax from here and installed the ducer using the "in the hull" method with GOOP.

First installation was done without any foam cutout. It was cured for 2 days and then tested with only the temperature showing.

Second installation was done using the "in the hull" method but this time I used a foam with the ducer cutout. Mounted the foam first with GOOP, waited awhile, then apply GOOP inside the cutout and mounted the ducer with weight on top. I didnt have a chance to test it out yet but was concern if I'm installing it the right way.

Feedback is greatly appreciated.
Thanks in advance BWE!
