Ive never changed a skin fitting

Can't see that Sika would attack the Nasa, but then that is cheap gear anyway that I wouldn't ever purchase it myself, indeed I would be questioning the quality of any under water fitting where the maker is concerned by what sealant is applied. I would not use epoxy because I like some flexibility in hull fittings. Hence the provision of a 'gasket' by my method.

I agree re: the principle of a part so seemingly unsuitable for marine use - but plenty do install them. Ours is completely glassed in inside.

At the moment there's a navman fitted but looking at connecting a transducer to the Garmin Echomap chartplotter, but with Oct 24th fast approaching I may have to put it off till the next lift out.
