[CA] Transducer Problem?

[joe-al]

I have an aluminum Ranger RT188 bass fishing boat with a Dragonfly 7 Pro fishfinder installed. I would like some assistance in determining the correct location to mount the transducer. I have good depth indication at speeds less than about 6 mph, but above that i get a blank/snowy screen with no bottom and no digital depth indication. I have attached some pictures of the current location of the transducer and the boat transom. The 1702.PDF file has some notes about the bottom of the hull where the transducer is now located; the anti-porpoising angle piece is about 1/2 in. high and welded to the hull, and the transducer is directly in front of it. I know i need to move the transducer away from its current location, i just want to make sure i don't end up moving it more than once. If you could provide some suggestions on a better (best) location, it would be most appreciated.
