I am interested in buying a Hunter 37 Legend, probably around '87-'89 vintage. There are quite a lot out there but I'd be interested in hearing from owners or previous owners regarding any potential problems to look out for when inspecting the boat. Also, on a more general topic, what's considered the life of a diesel engine in a sailboat. Obviously this can vary depending on how well they are looked after but when you see an engine with, say, 1500 hrs or so, how much life might be left in it?
