Depends on what the hull is made of. A cored hull will not work with a shoot thru transducer.
Here is how to check. Take fuse out of your bilge pump, and get about 4 inches of water in the bottom. Lay your new transducer in the water, and see if it works. Try different spots.
Once you find out it will work, get rid of the water, clean area real good, using alcohol, than epoxy the transducer in. Make sure you get every air bubble out of the epoxy, or you will get false readings. Good luck.
I know its not cored where i want to put it its solid fiberglass about 1/2" thick. The boats on a trailer right now and id like to have it in and working by the time its in the water.
