I am looking at buying a sportfish that has two 2001 1050 MANS, with 2500 hours on them. I was wondering if anyone here knows at what point the engines need to be rebuilt. The are running very strong right now, and everything checks out good on them, but with that much time I want to be ready to write the check for the overhaul. Any sharing of advice or experience is appreciated, and if anyone has any idea of the overhaul cost, that would be helpfull. Thanks for your time.
