Check with a dealer or Hunter!
Jeff:You can check with a Hunter Dealer or Hunter Marine.You can also test this yourself. By placing the transducer on the hull with some silicone, peanut butter or other material that will hold it in place you can tell if it is going to work or not. If your hull is NOT solid (which I do not think yours is, it will not work properly. You will be getting a signal from the outside hull.
