    Check under the boat for any strakes or chines anywhere close to the path the water takes passing under the hull.
    Most likely culprit is air travelling along the bottom of the hull. Moving the transducer further inboard may very likely rectify the issue.
    The boat has a flat clean bottom..no strakes or anything else down there. The inboard edge of the transducer is 14 1/8 inches from the center line of the lower unit. I was concerned that mounting it too far inboard might have an effect on the prop function...but I don't know if that is even a concern. How much further inboard do you think I could/should move it? It was installed per instructions guidelines but I suppose there can always be variables to consider. I'm appreciating everyone's input!

      Is it possible that the transducer cable has been damaged somewhere due to vibration, chafing etc?

        I guess it is possible, but I doubt it. Everything is secured and protected throughout the cable run...certainly nothing flopping around.

          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 instalation 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 transducer.

            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.

              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.
              Thanks for the tip. I haven't been using that, it's worth a shot. I did look at both the male and female pins on the connector and they looked crud free. Anyone have any tips for cleaning the small female pins on the connector?

                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? Usually when underway, you are heading into and through deeper water. If you have kids on the boat, they love to mess with your settings Also, I hope you are using a split screen or have another chartplotter set to gps map so you can avoid asterisks = rocks!

                  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:

                    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 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.

                                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.
