[Tiara Open] 2018 43' open, trying to find make of windshield wipers that need replacing.

I have a 2018 43" open Tiara and I need to replace the rubber wiper blades.  There is no make or model info on the blades and not sure where i can get them. Auto supply stores are telling me i need marine stainless steel blades because in salt water they will rust away really quick.  Any info would be greatly appreciated.  Thank you
