As previously mentioned, corrosion is likely more of a concern with a salt water boat.

Another place where corrosion can be a concern is in the engine itself. Make sure you know the difference between a raw-water cooled system and a fresh water cooled system and which is on the particularly engines you're looking at.

Raw water cooled engines use the sea water pumped in to the boat to cool the engine directly, with no heat exchanger. So, if you're in salt water, the salt water is fed through the engine block. That can be bad news because of corrosion.

Fresh water cooled systems use a heat exchanger. No salt water gets into the engine itself, rather only in the heat exchanger and exhaust. Most newer/modern engines use the enclosed fresh water cooling system with a heat exchanger and coolant, but there are still many raw water cooled sailboats on the market.
