Transducer location Deep V NorthCoast 255HT

[PeterG]

Hello, I would like to get advice on where to put Transducers on a NorthCoast Deep V 255HT with twin Yamahas on a bracket. Some hull shots attached. I would like to have DFF 3D and Chirp. Since it is a trailer boat probably rule out the a transducer with Fairing block. I probably need to do a Transom Mount or a Pocket Mount. I intend to use TZT XL MFDs. Please let me know if anyone has previous experience or best solution for Deep V boat approx 30 ft with motor bracket...Thanks

The best source for transducer placement is the boat manufacturer or the dealer. Because the hull is stepped you cannot put a transom mount on the motor bracket (due to air bubbles created by the step). A transom mount would have to go on the step.

There are low profile-tilted element transducers available such as this one... https://furunousa.com/en/products/b175hw--20

Once again the best source is the boat manufacturer or dealer for transducer placement

One thing to bear in mind is that the DFF-3D transducer needs to be able to "see" out about 120 degrees or you will lose some of the width of coverage. I am a big fan of pocket mounting because generally the water flow will be cleanest especially at planing speeds. If you have a good fibreglass guy and the bilge area 12" or so forward of the transom is accessible, a pocket on the keel will likely be the best option.

You could pocket mount a dedicated DFF-3D transducer such as the 165T-B54 and use flush tilted element CHIRP transducers on either side of the keel. That's what I have and it works great. In the photo below, you can see my 165T-B54 in the center and B175H and B175L CHIRP transducers to either side. My boat is cold-molded wood so I have a large structural wooden keel, which made it more complicated than you will face in a fibreglass boat. My installation was done by the boat builder.

There are a bunch of choices for the CHIRP transducers depending upon what types of fishing you do most.

Many Thanks for your information and I hope you had a nice Thanksgiving. I was wondering if Furuno or anyone else makes a "box" for installing a pocket mount transducer for the
Furuno Transducer
165T/275LHW-12p
I spoke to a fiberglass guy and he said it would be easier if there were a pre-made box. Thank You

all transducer boxes that i have seen are custom made for each transducer. a good fiberglass guy can do it with his eyes closed. so i would use a very good fiberglass guy as the fitment and placement of the transducer is key for a clean picture.

Usually they make a wood or rigid foam plug the size and shape of the transducer and form the fibreglass housing on it, which is then glassed to the hull after the opening has been cut. It's really pretty simple. A friend of mine even did it himself.
