I have an 18’ CC aluminum(Alumacraft) boat that loses it depth readings at speeds over 15 MPH. The boat has several “ribs” running lengthwise from the bow front to the rear transom. The transducer is transom mounted and is located between two of these ribs. I have had two different Lowrance units on the boat and both performed the same as described above. My question is: Can you mount a transducer to shoot thru the hull on an aluminum boat? I have done in the past with fiberglass boats but not aluminum and it worked very well.
Yep! You need a transducer that is specially designed for Aluminum!

This is an old common problem,
Don’t think a shoot thru will work on ribbed alum. Alum ribbed boats
create lot of turbulence bubbles under boat. A thru hull might work
but requires different type trans. and cutting hole in bottom of boat. IMO I would first try to mount (temporarily if possible) a
bracket to get trans a little deeper in water. Good luck!!!

Neither did I gail. Google is your friend:wink:
Try tilting the transducer down one notch. Helped mine out.
I thank everyone for their input and will try the suggestions mentioned!
I have been led to believe that a transducer will shoot thru anything except air.
