Welcome to the site Chris, I’m going to move your post to a more active board, so you will get more replies. I’ll attach a pic with locations circled in red, where I think would be a two good location but without more info it’s hard to say for sure.
Yep right side due to the prop turbulence
He also posted this additional info on another forum:
"It is a fiberglass pontoon boat. I am thinking on the back of the starboard pontoon but this area is not flat. It has a slight curve to it. Not sure how this would affect usability. This would also be easier to hit when swimming.

Hello, I wanted to see if anyone has a suggestion for the best placement of my Lowrance 3-1 Transducer for my boat. My boat is a 1989 Magic Legend 240. Not a direct fishing boat but is a good all around boat.
Any suggestions would be appreciated.
Chris
If you need a different picture please ask. If you can mark on an image and upload it that would be best. Thanks
