SI Transom Transducer Location (Please Help)

[IceNitro]

I mounted my HB SI transducer high because I fish shallow a lot and I wanted it somewhat protected. I am always bouncing, dragging or scraping on rock or timber. Now I am tired of it cutting out at higher speeds. I could use some advice on optional mounting locations and/or devices.
Its a 1996 Nitro 170 TF.
