Thread: Jon Boat Transducer Transom Mounting Location

Ok Rickie and Scout, here are the picks and buck rivet I used. On a side note the absidy cable is defective from Hummingbird. They have had a bad batch here lately. They are sending one by mail that's been tested.

Ok.

Where did you get the mounting board Earl ... ??

Some may find that info helpful also ...

Rickie

I finally got mine on last week.

These newer Alumacraft jon boats have the rear bench extended to the transom on the sides so there is not access to the inner/sideportion of the transom for using nuts/bolts or rivets. So I decided to just attach it solely with 3M 5200. That stuff is messy but it is solidly on there.

To prep the boat, I just lined the board up where I wanted it and put masking tape around it. I Cleaned the area with a damp cloth and then followed it by wiping with acetone. I then lightly sanded the area and re-wiped with acetone. To prep the board, I used a small router to cut some 3/16" groves in the backside, then roughed it up some with bi-metal jigsaw blade by holding the blade in my hand, then finished it off with some coarse sandpaper and acetone wipe down. I would have used a dovetail router bit but apparently didn't have one.

I applied a liberal amount of the 5200 to the board and put it in place and clamped a 2x6 to the top of the transom and to the rear trailer cross member to hold it in place. I tapped the board into the exact location and leveled it and then removed the tape. This was fast cure 5200 so it only took a day to cure.







It doesn't look perfect and I got a little 5200 on the outside of the board and on the transom but that's the price you pay when you tackle a project on a weeknight when the days are shorter. Even with lights its hard to beat regular sunlight. I have the transducer mounted as well but don't have a pic yet. I'll add one of the final product soon.

Looks fine to me.
