I kinda figure this thing has gone bad but I figured I would ask and see if anyone has had a similar issue.

My graph (Lowrance X51) was constantly loosing the bottom and would read like 2' constantly then all of a sudden it would find the actual bottom. I had a new 522C and called Lowrance and they said the transducer was universal so I installed the 522. The same problem exists. I checked to make sure it was solidly epoxied to the hull and all the electrical connections seem good. The GPS works without any issues so I dont think its loosing power. Anyone ever have a transducer go bad or do I possibly have another issue. The X51 worked great for several years and this condition just popped up one day.

Any ideas?

This might sound stupid, but next time you go to the lake put a couple cups of water down the drain hole in the floor 4 or 5 good size cups. What might be happening is that your transducer could be sitting over a small air pocket in the hull, not letting it recieve a good signal. If that doesn't work then try putting your graph on one of your buddies boats and see if it works

I put a whole new graph and got the same results. I will try the water trick and se if it works. But since it worked well in the past Im not sure.

It happened to me not to long ago same thing. Talked to I think her name was Linda at Lowrance boy did she know her stuff. I have a 332C at the consul did the same as yours
my trans was epoxied to the bottom of the hull bought new one and held it in my hand over the side of the boat fixed the problem. I did not want to glue a new one in the hull.
I have a 10" manual jack plate on a ZX-225 and right next to the jack bolt is a 1/4" hole
I mounted the skimmer trans /temp using the chrome bracket for the transom bolted it up
works great at low speed till the water in the jack plate starts to aerate up to about 5mph any faster than that the units a speedo
