    I wanted to install a fish finder on my old 1957 14’ V-bottom aluminum boat, but I didn’t want to drill any holes in the hull because the hull is in excellence shape.

    So what I did was make a mounting bracket out of ¾" plywood and mount it on the boat using one of the two oarlocks.

    I then mounted the fish finder display head onto the mounting bracket.

    After quite a bit of pondering about how to mount the fish finder’s transducer, I decided to use two of the bolts on the transom’s rear plywood to hold a bracket made of ¾" plywood.

    Not wanting to cut a hole in the transom for the fish finder’s transducer’s cord, I installed the transducer on the plywood bracket and ran the cord over the top of the transom. Not too pretty, but it works!

    In the above photo you can see the ¾" spacer that I epoxied onto the lower backside of the transducer’s mounting bracket.

    Simple installation without any new holes!:roll_eyes:

    I mounted mine in a similar manner. I just used a scrap piece of plywood and clamped it onto the boat. It's not pretty, but it works!

    Bill I have an old simi v boat made just like yours,no dents or dings and it's the dryest boat I've seen.I don't blame you I wouldn't want to drill holes in mine eather.

    My boat was given to me about 10 years by my father in law.he had bought a house next to his and I helped clean up the place for him.The boat was there when he bought it and I know he never saw it up close because the old man couldn't walk to good and was having to use a walker I thought it was wild because the boats name is Miss Margie.(Margie is his daughter's(my wife) name)

    Jim, there is no doubt you were meant to have that boat!

    By the way, my old boat doesn't leak anywhere...except the drain plug in the floor when I forget to tighten it down!:tounge_out:

    Those old boats were built stout!:roll_eyes:

    Well Old Bill once again you did a quality job. Mostly I sit and dream about the next project while you get her done. I am still worrying about the depth of paint left in that red paint can, how’s it coming? Are you going to have to hang up the brush, change colors, or can you buy another can of that color? Sure hope it doesn't mean the end of projects.
    Luck

    Ha! Jerome, if you only knew the many, many projects I have dreamed about doing...and that were never accomplished!

    I just checked and found that I still have 1/2 can of that lovely red paint left! However, since it's just one of Ace Hardware's stock paints...I should have an unlimited supply...if Ace stays in business!:smile2:

    Best wishes,

    Bill

    Is there anyway how to mount the fish finder’s transducer without screws in the boat or plywood?

    Well, john103, I'm sure that there are better ways, but, all I can think of is to make a board out of some material...something like shown below.

    http://oomur.pair.com/wwpotter/images/richline%20transducer mounted.jpg

    Mount your transducer on the board and then attach it to your boat's transom with a C-clamp like dr__love2121 "Ricky" did on his boat. Should work OK!

    Maybe someone else will come up with a better idea?

    Good luck,

    Bill

    I expect that you might be able to "epoxy" it on, but then you are kind of stuck with it. (pun intended):big_smile:
