My boat came with a Garmin Echo 101 and would freeze up when exceeding 12 to 14 MPH. Both Garmin and my dealer told me that there was nothing that could be done to improve its functionality but based upon comments made on this site, I thought I'd try to make some adjustments myself.
Because my boat sits in the water all season, my window was rather narrow so I showed up at my dealer a bit early (they deliver from storage to water) to see what my options might be. As I was playing around with the transducer, my driver came up and asked if he could help. I explained the situation so he came back with a drill and proceeded to move the transducer mount from the center of the port tune approximately an inch further outboard and about a 1/2" lower. With the change, part (not all) of the transducer is now slightly lower than the toon.
Not sure of what, if anything, would change, we splashed the boat and I took off across the lake at roughly 5000 RPM (my speedometer now isn't working) and was pleasantly surprised to look down and see my Garmin actually working!
So, for those of you suffering similar problems, I think this might help you out as well.
