Garmin 93sv losing depth and sonar

[DC14]

When I drive over 10mph, I loose my depth and sonar. I have moved the transducer up and down on the transom without a change. Even when driving 5 mph, i get some interference and begin to loose depth and sonar. Once I come to a stop, it comes right back. Any ideas?.

Anything that causes bubbles in front of the transducer will make it loose bottom. Trim tab, mounted to high or at the wrong angle.
Did it work before and not now, or is it a new install?

Yeah, we need to know exactly where its installed. Post some pics of the transom and where the ducer is placed. Be sure to get a pic of the bottom of the hull too. We need to see any steps, strakes, water intakes, etc.
