Like Pete says, at that price, assuming the engine is alright (or you can fix it if not), and assuming the boats not in a real bad state, go for it.
should be easy ish to turn into a centre console assuming it is currently the ski boat type. Just take off the dash, buy or make the centre console and fit it. You can leave the bow dodger on or remove it. Very common operation on the 4m over here, I think we don't have so many of the ski boat setup around.
