We sometimes debate the wisdom of using a minisplit system for heating and air conditioning on our boats, or an RV unit. I have noted that if you do so you have to consider it a throw away item because the salt water environment will ultimately corrode it out.
So here is a picture of a minisplit condenser. It is located 100 or more yards from the shore and at about a 100' elevation in a hotel in Bermuda. It is not exposed directly to salt spray, just high humidity. I can't be sure of the age, but it is hooked up to a Samsung Smart Inverter interior unit that looks pristine. I think they have only made these for the last 5 years or so.
They are efficient and relatively cheap (well compared to a raw water cooled marine unit) but you need to be prepared to replace at least the outdoor unit every 5 or so years. If they made the housing out of SS it would last longer, but I suspect the market for such will be small. And FWIW the one pictured is still working.
