Last fall the power cable on my Eagle Strata 128 depth finder went out, so over the winter I bought a new cable and transducer. The old transducer was installed by a hack. The power cable worked great, but my original irritation still exists, and this is where I'm asking for help. My depth finder only works when I'm at trolling speed or below. According to the manual, it should work when on plane. The transducer is parrallel to the hull and the bottom of the transducer is even with the bottom of the hull. How do I get the depth finder to read when I'm on plane? I don't use it as a fish finder, only for depth as I want to know what's under me and my river is about as skinny as Karen Carpenter. Does my transducer need to be below the hull? Does the fact that I'm running a jet have something to do with the problem? Help?
