[CA] [CA11] system configuration question

[djw99]

I've just procured an older 26 foot center console boat. It has a raymarine st60 tridata instrument installed and what I think is a B44 depth/temp/speed transducer. The transducer has a large fairing block that is getting in the way of my trailer so I'm looking to replace it with a flush mount transducer. I'd like to keep my speed/temp/depth data and the st60 instrument but I'd also like to be able to add a more modern mfd in the future. Any idea what transducers I would need and how would I network them to both an st60 tridata and in the future an a-series mfd or equivalent?

thanks in advance for any help.
