Hi mate,
I have the same transducer. I will send you pics of mine if you want. I don't get a rooster tail like you.
From what I see, it looks to far down. Mine is a lot higher, so that round curve on the transducer sits level with the boat.
Also, unless it is the angle, the transducer doesn't look straight.
Another point, I personally would of moved the transducer to the right as the bottom of the boat seems a little flatter there and you won't get much turbulance.
