Posted: 14 Apr 2011 at 7:30pm

I am hoping that a few Dolphin owners might like to share some info about the placement of their depth sounder transducers. I am adding a depth sounder as part of a total restoration of my new Dolphin. Would love to hear where others have put their transducers, either through-hull or in-hull, and had success with the placement.

Most Warmly, J

Hi J
My transducer is mounted inside the locker below the starboard quarterberth. The hull here is solid fiberglass. The transducer is inside the boat and bedded in epoxy. I think it has worked fine for 15 years

I tried this experimenting with putting my sounder inside the hull below my galley unit in a recess. I sat it against the hull in a dam of water, As the suggestions are to trial it. However was put off with the ticking of the sounder, Very audilble. Does anyone have the same issue. Ta

It came with the boat. Its an Eagle, Cuda 128. an oldie, It hangs off the stern on a bracket at the mo. Me being me, I see that bracket and wire coming out of the transom everytime, and want to change it
But havent the funds to go buy a flash one. HAHA
Im trying to get a cover for the unit as well so I can mount it in the cockpit bulkhead, instead of sitting on a bracket on top of the cabin. Im prob being pedantic. Oh well!!!!!!!!!!!!
When trialling, I used the same method as the instructions gave, so didnt wonder off track.

I recently replaced and old transducer in the starboard locker near the batteries. Since the hull is thick I had to order a upgraded one through NorCross (I had purchased a Hawkeye kit from West Marine...NorCross gave me a $40 credit on the kit transducer which was not strong enough to shoot through the hull). I followed instructions and placed it in a tube epoxied to the installation place then added a small amount of mineral oil. I then adjusted the angel of transducer to remain level as possible with the rise of the bulkhead. It works great and was fairly easy once I called the company several times (they were very helpful). Their number is 888-766-7276. Good luck.

Just added a new Humminbird thru hull transducer. Placed it 8" forward 20" starboard of mast if that makes sense! Leveled with a block, ready for a dual frequency head unit, most likely a Piranhamax 170.
