I upgraded my 330 with dual Garmin 1243XSV MFDs. In addition I changed my radar to one of the Fantom solid-state radars. I previously had one of the older magnetron 18 Garmin radar and it was not nearly as sensitive and had less functions.The functions are amazing and easy to use. As an old retired Coast Guard officer I find these electronics packages to be almost unfair. They take all of the skill out of navigation and seamanship it seems! I have one through hull transducer and one GT 56 transom mount that provide sidescan works great! Your hull is similar if not identical to mine. Highly recommend a package that includes at least 12 inch displays For us more senior navigators, I am 72, 18” might be better but 2-12s fit in my console box. Good luck!
