Echosounder Stops Working at Boat Speed of 12-Nautical Miles Per Hour

I have a Garmin echosounder with transom mounted transducer. I have noticed that the echosounder stops giving me accurate depths when I'm traveling over 12-nautical miles per hour. Garmin tech support wasn't much help. I have cleaned the [transducer] and confirmed that I have the latest firmware. [Begins a survey to see if other users of Garmin echosounders are limited to 12-nautical miles per hour or the echosounder stops functioning.

It's the transducer mounting. Make sure it is angled a wee bit forward to ensure a smooth flow of water over the face of it.

Thanks Tom. What do you mean by move it forward? The transducer can move, but the bracket is mounted.

Angle it down about 4 degrees.

I am very surprised that GARMIN technical support could not offer any advice on this problem. The most likely cause of loss of echosounder function at higher boats speeds is the location and mounting of the transducer.
