Hatteras and old Detroit Diesels
Old Hats and Detroit DieselsWe've been looking for boats for a while and finally found one through Yacht World we really loved. It's beautiful and seemingly extremely well maintained.We cancelled the survey due to less than positive findings on removing airboxes and scoping cylinders on 12V92s rated for 1040hp. These engines have low ours since major overhaul, but that overhaul was more than 20 years ago. Issues found on scoping the cylinders included no or little cross hatching, heat spots, lack of tinning, and scoring. Our engine surveyor recommended compression testing of all cylinders with a full borescope (this requires removing injectors, and is no small or quick task).Owners finally produced the service records we had been requesting after we shared the findings from our engine surveyor. Service records from not long after the current owners purchased the boat in 2018 included: "crank shaft leaking, owner not going to repair" as well as "# 5R top ring bad. Owner not going to repair ring at this time". All agreed to start the mains to see if they smoked (they do and not just on start). Thankfully they shared this service record. Needless to say the owners could not produce records showing these costly repairs have been made. We're sure they run, and likely could for a while, they are 2 stroke Detroits after all but better to find out before making their problem, our problem. Buyer beware, what looks great isn't always. This boat is still out there for sale and may need full main engines overhauled. All overhauls aren't equal, and all parts aren't equal. Hire GOOD surveyors. Your hull surveyor should KNOW older boats and your engine surveyor should KNOW engines being surveyed.We still have some hope this may work out but it’s yet to be seen.
