Hey Oldfauser, I am planning to do the same, swap the old Datamarine insturments with the new Raymarine DST800 and some wireless ones. How did your transducer replacement go? Was it enough to fill the gap with marine sealent or did you have to do any other prep work? Any feedback helps
we did replace the speed transducer with a new DST800. we used bedding compound last year. We did have a little "wetness" around the fitting so we are going to re-bed it this year with PL 4200, but all in all it worked fine. Just be sure to get it fully packed
The old depth transducer was a "bear" to get out. Had to cut it. I wanted to get all of the Datamarine parts and sending units out as i sent them to DMI for recycling! I used the original Datamarine thru-hull from the speed with the blank plug to fill the depth fitting hole as the Raymarine DST800 unit does depth, speed and temp in one thru hull.
we went with wired as the 32-3 has wire runs for the network cables! Also helping as this year we are adding an Axiom 7 at the helm along with a Raspberry PI to help with the AIS receiver, all tied into the Raymarine Seatalk ng network.
feel free to PM me for my phone number to discuss!
