Hedgehog1957-

I'm going through the same set of decisions right now. Do a search here for "transducer", you'll get plenty of ideas and pros and cons. The "shoot through the hull" option looks intriguing. The problem is no temperature readings. So I might finally end up with a through hull transducer, to get temps as well as soundings.

Another option is to glue (5200, 4200, epoxy, marine-tex, etc) a starboard or acrylic plate to the appropriate region on the transom, and screw the transducer to that. No holes in the transom that way, and the transducer position can be tweaked and moved a little if need be. My problem with the transom mount is running the wire up and over the closed I/O transom. I don't think running it through a scupper hole is a good idea. Decisions, decisions.

Any advice from the group on through hull transducer choices?
