Hey, Barry. the problem is almost certainly transducer mounting. The face of the 'ducer must be fully wetted to send and recieive successfully. Check angle and proximity to bottom edge of transom.<br /><br />Good luck.<br /><br />Red sky at night. . . <br />JB

I have had the same problem & JB is correct about the transducer mounting. <br />My transducer was plenty low (about 1/2" below the hull) & I still could not get a consistant signal above 1/2 throttle. I found that it was mounted directly inline with a rib that ran down the length of the hull. This causes lots of tiny air bubbles to pass under the transducer which can result in signal loss. <br /><br />I moved it over a few inches and it works ine now.<br />Good luck!

JB... just a question, I have the same depthfinder in my rig... & identical problem w/ WOT...<br /><br />Old bass fisherman friend of mine told me to epoxy this to the bottom of my boat while I was doing my installation for thru hull mounting.<br /><br />What are your thoughts on this subject... Look forward to your reply.<br /><br /><br /><br />------------------<br />"Keep it between the Bouys" & Good Luck!!!<br /><br />fone_man
