I am in the process of redoing my skiff. I am going to install a GPS/Fish Finder and was trying to figure out my best option for the transducer cable. The plug end requires an one inch hole to get it through the transom. I figure I would drill that hole well above the water line. My question is what is the best way to seal that in? I could epoxy it, sand, paint and put a clam shell on it. Problem there is if I need to remove the transducer for any reason it would be a real pain to replace. Do they make a rubber compression fitting similar to a transom plug that as it tightens it squeezes around the wire and plugs the hole? I was thinking I could try and fabricate something but wanted to see what other guys have done. Thanks!
