Thread: Jon Boat Transducer Transom Mounting Location

Slower speed scanning is usually not an issue because the boat sits in the water lower and not as likely to create aerated water at the slower speed ...

As the boat speed increases, rivets can be challenging sometimes when trying to find a suitable mounting location ...

Some have fabricated a temporary mounting board that can be securely C-clamped to the transom for testing for placement options ...

My guess would be exact center between 2 strakes in your case ...

That is some good info. The plastic mounting board I purchased is 12" wide so I may be able to place it on my transom so it captures the middle of the center "gap" and the outermost "gap". I could then try both locations.

And as you mentioned the SI and DI functions would be used off of plane so I would agree, turbulence would be less and hopefully negligible for accurate readings. I guess ideally I could put the SI transducer in the center gap and get a regular sonar transducer to put on the outermost gap to get high speed depth readings.

But that aside, is there any reason to not place the transducer in the outermost strake gap (see my 4th picture)? That location is far away from the prop and has a strip clear of rivets...but would also only be 3-4 inches from the side. I'm not sure if being mounted that close to the edge is a potential issue or not. But that location seems like it would the best location given the hull design assuming that close to the edge is ok.

I like the idea of a testing board to mount to the transom though. I will give that a shot before I do anything I think. I guess it's just as simple as using a really rigid board and clamping it on?

Correct ... Just use a board stiff enough ...and C-clamp it well ...

You wouldn't want it to come loose and get into the prop ...

Good luck is a requirement.

Definitely not something I have! LOL

Scout I did the same thing you've doing on the about same size boat. It will work. But instead of screwing the board in, I riveted it with 1/4 buck head rivets likes in the boat already. Water tight, no leaks. Got them at fastenal in CULLMAN near you. Same rivets they use in 52 " trailers ( semi truck). Or you can get them at Fleetpride.

Earl ... Could you post some pix of your mounting board/xducer installation ...??

It may help some following this thread ...
