Might look it up. I installed my new sounder tranny with sikiflex and so far all I get for fish is shapeless blobs, no fish arches. I haven't played with the sensitivity yet, but I might be looking at reinstalling it. A wet install is probably what I will end up with. With this duct seal stuff it would make it easy. I was thinking of using a small plastic container, cutting the bottom off and sealing the edges with either this duct seal or sikiflex and sealing the lid after fitting the cable through it, then the water could be permanent and never leak. You could use fresh water and even store it upside down without ever needing to replace it unless the water went 'off' somehow, which I doubt.
Anyone else done something like this?
Water lapping against the hull, warm gentle breeze, fish straining on the line... how much sick leave do I have?
