Hi everyone,


A few weeks back I picked up a nice little fishing boat. I also just got a new Humminbird Helix 7 w gps/si/di. I am new to the side imaging and have no idea where to mount the transducer. Surely I can’t be the first one to do this?!? Does anyone have any tips, or pictures of their install on a similar boat to mine. It’s a 70s Mirrocraft, 14ft. Any help you might have would be awesome.

3M 5200 bedding compound will adhere but it ain't exactly an adhesive. What it will do is make a waterproof seal on the the two bolt holes you drill in your hull below the waterline. I would use a piece of 3/4" plywood backing on the inside to prevent the bolts from pulling through. After you drill your hull with the plate clamped in place,  generously apply your 3M 5200 on both the inside backing plywood and the transducer mounting plate on the outside of the boat. Screw or bolt through using washers until the 5200 starts squeezing out, then scrape the excess off with a putty knife.

google transducer mounting board, you'll get an idea of what's been suggested, plus some youtube examples

Mounting board - a roughly 8"x8" piece of "starboard". You could use a thick piece of plastic cutting board....Sealer - 3M 5200 marine adhesive/sealant is about as permanent as it gets.

Agree with others have said. Use mounting plate so when/if you want to move the transducer or change it in the future you aren't swiss cheesing your boat. Mounting the plate isn't hard either. Feels wrong drilling holes in a boat but filling the hole with sealant before adding the mounting hardware seals the holes right up. Also installing the transducer on the side with less prop disturbance is always recommended. That is based on the clock rotation of the prop. When you usually mount a transducer you also take into consideration where the stern waterline is at plaining speed so the transducer rides the least aerated water. However with these side imagining transducers I have never seen anyone get them to work at high speed so I wouldn't even worry about getting them to work at plaining speeds. Most guys I talk to have a second cheaper high speed transducer to see things while on plain but I dont have experience with those.

I've got a 14fter too and i bought a suction cup mount for mine and it works just fine. I think i bought it from Gander mountain.

X 2 on the mounting board. There are a lot of videos online on mounting tips. Level your transducer according to how your boat sits underway to get the best images...these are from my helix 7 mega...

You have a good quality side imaging unit that can change how you fish. Unfortunantly the more variables you add like clamps and posts holding the transducer the more problems you can have. The unit will be more consistent mounted to the transom. for 20.00 you can get a transom board so that in the future you are not putting any new holes in your transom.

I guess what I am asking is other than bolting it to the boat has anyone ever used any of the clamp on brackets with success. I don’t know if those types would be a pain with the side imaging. Or is bolting it to the boat the way to go.
