Praba -Here is what I did - works perfectly!Ducer Mounting Submitted by Rob Rich on 01/15 at 11:37AM regarding Catalina 30 Walter -Best thing to do is to take the ducer, connect it to your display and power the system.Dip the ducer in water and then depress it against the hull at the approximate mounting location. Press it hard against the hull, too. Make sure the mounting location is also moist. Move the ducer around until you get a good picture on your depthfinder/fishfinder. In doing this, you will find a good area on the hull that is free of airbubbles in the layup. Once you have a solid location, mark it and then make a dam (quarter-inch bead or larger) of RTV/Silicone ontop of your marking. Allow this to dry. Then mix the epoxy, smear some smoothly across the face of the transducer, and pour the rest slowly into the RTV dam. It should be like filling a mini-swimming pool with epoxy. Be sure not to get any airbubbles in the epoxy (read

our slowly). Then, just press the ducer into the epoxy, twisting slowly, and hold pressure on it for about 10 minutes. You'd be surprised how easy it is, and how well it works!If you need further or more specific info - feel free to e-mail me.Best of luck -Rob
