Sail Rock 28 Posted May 30, 2015 Share Posted May 30, 2015 Hi I am going to replace an existing Airmar depth transducer with a new one - same size hole fortunately, 50mm, through the hull . Can anyone provide advice on what type of sealant to use between the new transducer and the hull? Some posts say 3M 5200 is the business, others say no way! Then there is 3M 4200, various Sika products or fixing it permanently with epoxy. Suggestions / advice from anyone with experience of having done this would be welcome ...

Tim C 23 Posted June 1, 2015 Share Posted June 1, 2015 Epoxy them in. When it does come time to replace them, then a few solid taps is likely to break the epoxy bond and the fitting comes out. With 5200 etc it is a battle all the way, or a hole saw. Quote Link to post Share on other sites
