Hi all,
Greetings . I own a 2004 Grady-White Bimini 306 and I'm planning to install an Airmar B175HW 20° tilt thru-hull running on Simrad. Most of my fishing , mostly in shallow to mid-depth water, want strong target detail and a clean bottom at trolling and cruising speeds.


I measured the deadrise at my planned location with an angle finder: 19.5°, so the 20° model looks like a perfect match. Photo of the location attached

I am not sure what I am looking at. What is that pocket and where it? It looks like there was some other transducer mounted there. That pocket may create turbulence that could affect the proposed transducer.
 
I think I'd move the location a little further away from that pocket.

I don't know if we're looking fore or aft but there appears to be something else not too far away - it's in the lower section of your picture.
 
I want to use flush mount transducer I test both of design I found flush mount more better
