This reminds me that I fixed a similar problem in year 14 of the age of my now 40 year old Taiwanese boat.
Most of the serious issues that relate to the origins of the boat will have shown up long ago. Any that have not been repaired by now are not that serious.
3500 engine hours, if accurate (check hour meter for signs that it is not original) is an average of less than 100/yr, typical usage in many parts of the world, but you do need to know where the boat lived for the majority of its lifetime. A comprehensive logbook helps, anything less leads to a lot of guesswork.
