Re: Sounder: Shooting through plywood
Stop,<br /><br />No, you can not shoot through plywood with an in-hull transducer, and it doesn't matter if you have the bilge partially flooded or not nore does it matter how you mount the in hull.<br /><br />I would be possible to simply cut out a window in the bottom of the hull and then build it back with glass and mount over top of the window, I wouldn't do it but you could. You'd be a lot better off going to a thru-hull or, as much as I dislike them, you could install a transom mounted transducer.<br /><br />I think I should tell you what I did before I installed my transducer. My boat has a solid glass bottom that is about 5/8" thick. It is an older boat. I didn't trust that my hull bottom's glass was completely solid, with no air bubbles in the laminate which would have reduced the capability of the transducer. Because of that before I mounted my in-hull I broke out the angle grinder and removed all of the glass in an area about a foot long and maybe 10" wide below where the transducer was to be mounted. This left the gel coat on the outside of course. Then I reglassed the area back to its original thickness plus a little bit to give a nearly flat surface for mounting. You could do the same thing to your hull if you wanted to. I think it took me about an hour and a half to do the glass work. Its not a big deal. My transducer mounts in a factory made tank that serves the same purpose as the PVC pipe that some folks use to mount there's. Mine is glued down to the hull bottom with 5200 to seal it, the tank itself if filled with mineral oil and the transducer is suspended above the glass in the liquid.<br /><br />Thom
