I bought a new boat and mounted a humminbird 859ci by myself and everything works awesome but after about 7.5 mph I loose my depth reading so I'm flying blind. I mounted my transducer in the same place as the previous owner, I'm just curious if there could be a setting or something I need to adjust or do I need to remount the transducer? The boat is a stratos 176xt.

You must be 15" from the prop or it will cause noise in the transducer. Also make sure its running in "clean" water. Then playi with it up and down a little, probably down. My birds were a little touchy too, but once I found the spot they read good to full speed (40 mph).

Make sure the transducer is even with and actualy an extension of the running bottom. Sounds like you may be lifting the transducer out of the water.

Either that or it's pointing back a little and at speed not getting the return signal.

Thanks guys R code sent me some pics and I think I've got to tilt forward and raise it on the transom just a tad. Can't wait I'm gonna fiddle with it this weekend. I've got an elite 7 hdi coming for the bow so I'm gonna spend a day and get both all functioning to my liking I let you know if I'm still struggling. Can't wait, I know I haven't had it long but I really loved this whole fiberglass thing last week.

Played with it a little this evening and still nothing. I just tilted it forward and tried, nothing. Went another click still nothing. I think I need to remove the bracket and drill new holes which I was really hoping not to do.

Get a transducer board and mount that to your boat with 2 Screws and a good marine sealant like 3m 5200 and mount your transducer to that so you don't have to keep putting holes in your boat.

had mine on the outside and had same problem, then went to using the one that was epoxied in the hull, no problems now even at full speeds (50+) not hard to do but I guess it only works on glass
