    It's not unheard of that the unit itself goes bad, been there done that!. If you've determined it's not a transducer related problem, contact the manufacturer. I spent an entire summer chasing what I thought was a transducer gremlin, turned out the unit itself (which was brand new) was bad and had to be re-built. If I hadn't spent almost $2K on the dang thing, it would be sitting at the bottom of PWS right now!

    A thought just occurred to me. In your second photo (Actually #1) am I seeing two transducers side by side?

    I'm wondering how close together they are.... If too close, turbulence from one could be interfering with the other when you're on step. Doesn't take much to make signals go haywire.

    From what I know, sure looks good to me. Folks with lots more experience out there and I'd defer to them, but I'd be learning something new in the process.

    surely someone has an opinion on my mount compared to the straight edge

    Yup snagged one from work today and it worked like a charm. Did my rigger connections too. Will post results next time I get the boat wet. Big thanks again to all.

    I made a couple changes. I left the paddle wheel where it was since it seems to function fine but did a little better job of filling in the radius between it and the transom bottom with sealant. I moved the transducer inboard about 3" using the 2 inboard holes to now be the outboard mounting holes. So I had to fill 2 holes and drill 2 new ones. This put me right at the 12" minimum per specs from the center line of the lower unit. I also lowered it about 1/8". Hopefully, this will make a difference.

    Even more basic, and I doubt this is the case as you seem to know your system well, but could the range setting be too shallow?

    Thats a good point Ron. Additionally, some (most?) units also have settings to switch between salt and fresh water. These darn new fangled computer thingies are way more complicated than the old days.

    I grabbed an old Mepps spinner and cut the shaft (main wire) just above the hook. Dump everything off the shaft and you have a very stiff small diameter rod. Square the end and use it to plunge the holes. Probably something better and more "official" but what else are you going to do with old spinners?roud:

    Maybe too basic, but did you use dieiectric silicone grease on the plug between the unit and the transducer wire? I wasn't doing that a few years back and developed symptoms similar to yours- complete blackout on step. Cleaned the terminals and added the dielectric goop, and no problems since.

    [QUOTE=breausaw;1391957]From looking at this picture your transducer looks like itís too far below the bottom of the hull, this could be a problem also. Normally it should be like ľ inch below the plain of the bottom at the leading edge than angle slightly down, check the installation specs.
    Like I said, perhaps itís just the orientation of the picture.

    The paddle wheel looks too low also.

    I would have someone look over the stern when youíre underway and see if wake radiates out from the paddle wheel to intersect with the transduer

    It is picture orientation. There is an index line down the side of the transducer...I used a bottle jack to hold a straight edge in place defining the hull bottom plane and from that, installed the 'ducer and paddle wheel per instruction manual. Good idea to have someone look over the stern while under way. So far, I'm the only person who's been on board the thing. Spread a little too thin, I guess.
