Add new question to the seller

Hi: I noticed this Mariah SC25 boat online and I have a couple of questions.
* It appears to be in south Florida so to your knowledge has it spent most of its life in fresh water or ocean?
* What is the condition of all the metal hardware? Any corrosion from salt, etc.?
* As far as the engine goes, what exactly was overhauled? All rings, valves, valve seats, rods, crank, bearings, etc. Was this done by a commercial shop and is there any documentation?
Thank You for your time.
