Default Thru hull transducer location- middle of boat ok?

Hi: If someone knows I would appreciate some help... I have a new striper 23 ft walk around with a 200 yamaha xb outboard. I am in the midst of trying to figure out my Airmar B175 1KW thru hull transducer location.

I just measured and there is a beautifully ventilated, easy access, roomy, and easy to wire area in the direct middle of the boat where I could mount the thru hull transducers. Boat is 22'8" centerline and the direct center of the installed transducer would be 11'6 from the back of the boat. Airmar recommends the back 1/4 of the boat as "best transducer location" so wondering if anyone knows about this. The bilge area looks really cramped and hard to access. Would be a dream if I could mount here with 100% performance. please help before I go drilling holes in the new boat! mahalo from Maui.

I would be scheptical about it. Unless it's a step hull that runs flat I'm afraid you'll get air between it and the water. Rear 1/4 sounds about right.

The key to a good thru hull install is placement in an area of positive hull to water contact while the boat is on plane.
Take the boat out..get on plane and you will see what area of the hull is still in good contact with the water.
For trolling speeds....much greater leeway.
