I hope this is OK, Question about Sea OX

[Mulv80]

The motor was a 1984 Evinrude 140. I have a 115 of the same year so I'm familar with it, However something about the deal wasnt right. I felt like the seller was trying to hide something. He told me that he replaced the water pump and t-stats himself a few years ago and that the reason it is overheating is probably because it needs to be done again. I asked myself, If this guy knows how to do a pump and t-stats then why wouldnt he do it prior to selling a motor that he knows is going to overheat. I guess some buyers just dont ask questions or know any better.
