Mount the transducer to the bottom of a 3/4 or 1" pvc pipe section. You can then use a 2x4 and screw in 3 of those broomstick holders, the ones you just push the broomstick into and it holds it. Then mount the 2x4 to your boat with a clamp. Just push in the pvc transducer arm. The holders will hold the transducer pvc firmly, but you can also raise it, lower it, or aim it very easily. Pops out easily too!
