Used plumbers putty so far to put the transducer in the forward lazarette in the cabin but it gets loose over time. Epoxy any good? Thoughts....?
Even if it does, it seems a bit permanent for a device that might break or need to be updated in several years. I've used silicone caulk, which worked fine and for me was a reasonable compromise between durability and removability.3M 5200 works?
