Transducer mounting best option?

[ggundersen3]

My 2006 Four Winns Horizon 180 was ordered from the factory without a depth finder/sounder. Faria and Humminbird both make several that will fit. There’s is the 2” cutout/space with the easily removed “blank” to mount the guage on the far left of the dash/instrument panel. 3 questions here: Is a through the hull or transom mount transducer better? What are pros and cons of each? If going with a transom mount type, should the transducer be mounted to some sort of block and the block mounted to the transom with some sort of waterproof/ underwater adhesive to avoid drilling in the fiberglass transom? Advice appreciated!

There is no benefit whatsoever to mount a transducer for a simple in-dash sounder on the transom. Mount it in the bilge and be done with it.

The different hull bottoms do require thought. About which will work best at all NORMAL planning speeds.

Does anyone have experience or an opinion on ordering marine electronics from BOE Marine electronics?? They seem to have name brand products at a decent price.

I have used a small piece of leftover composite exterior trim 3/4" thick that I used on my house. Applied the block with an exterior all-purpose construction adhesive. Stayed stuck to my last boat through the life of 3 transducers under extreme abuse for the entire 7 years I had it.

Are you using this just to read the depth, or are you needing to scan the are for fish or other details ? Just as a depth sounder only, shoot thru the hull if you can get it in a good position. If your needing underwater details then a transom mount is needed. With today's adhesive's , glueing on a block should be the way to go on a transom mount.
