in hull transducer

[helton333]

Anybody had any luck with adding a particular brand of in hull transducer for a depth reader. I purchased one from norcross but the small transducer will not shoot through. I wanted to make sure my next one would actually work.

I've had two boats with in-hull transducers (my Mastercraft doesn't have a depth gage) and they worked intermittently at best -- often going out on me just as I was entering the shallow water of course!

Just my experience, maybe others here have had some that actually worked.

If I ever buy a new depth sounder, it will be a transom-mount. I guess if you're putting it on a Mastercraft, the swim platform would hide/protect it(?)

thanks - I really want to try and make it work inside - I know some units work but we'll find out which ones. Thanks

I put a hummingbird on mine. It works fine

This is the one I have and it works great as a thru-hull. Just make sure you get all of the air bubbles out of the epoxy before setting your puck down.

I occassionally lose it at WOT but at those speeds I am not really relying on the depth guage. I think if I moved it back it would work flawlessly at any speed.

I have had Lowrance 3500's in my last two MC's and they work great.

Humminbird is the way to go as far as thru-hull transducer. Placement of this type of depth reader is important. You can't place it in an area where there is any "air" between the hull and the lake or any dead space between the bottom of the hull and inside of the hull. The location must have a solid(all the way to outside of the hull) area where there is no issue of air pockets or a possibility that the hull will be out of the water at any speed. You want it as close to the centerline of the boat as possible. Mine has never had any problems.

I have the same model epoxied about 5-6 inches to the right of the water pickup behind the transmission. I works 99% of the time. Normally only when in reverse when bubbles get sucked under will it blink.

From what I can tell it has been very accurate as well.

I think the location you installed your puck is the designed location. I installed mine to the port side of the drain in the bilge. Seems to work OK. It will flash when going over large waves.

That's exactly where I installed the puck in my first ProStar. I worked fine until it started to get bumpy then it was too far forward and would get air between the hull and the water.

My hummingbird puck is mounted to the port side of the tail end of my transmission. Works great till I hit big wakes and my drink starts to splash out.

I mounted mine very close to the steering cable mount, close to the rudder, centerline and a little starboard. I never have issues with wave action with this location.
