Fwiw, I replaced 2 thru hulls start of last season and in one installed a DST 800 and used 3m 4200 fast cure and it seems to have worked well.
I had a question about the they thru hull and found the customer support at Gemeco to be very good, they might be able to comment on the they hull placement. My guess is if aft the water flow may not be best for speed? https://www.gemeco.com/transducer-detail.php?transducer=DST800 Best regards, Lisle On Tue, Mar 23, 2021 at 2:38 AM Randy Stafford via CnC-List < cnc-list@cnc-list.com> wrote: > Listers, > > I appeal to your collective wisdom here.
