Seems that there are a few in the 3000 to 5000 hour motors in Nordhavn's out there.... most have less.
That sure is a difficult one to answer. So, perhaps thinking a bit as the manufacturer. Their 5 year (normal one plus extended 4) warranty is 2500 hours. Their first major service per their manuals is 2000 hours. This is when valve clearances and cleaning heat exchangers comes into play. So I'd consider something like double these numbers to be high and the time at which the first really major expenses might hit. 4000-5000 hours. By no means to I consider that a life though. I could see that as the point as worst case of a partial rebuild, and double that as the best case. Then double those numbers perhaps for a major rebuild.
So much is how well maintained along the way. I only have a feel for Lugger's because own them through owning Northern Lights generators. I'm a fan of Lugger's.
So if I'm looking at a Nordhavn, I'd expect to start having to spend some money around 2500, more substantial by 5000 hours. But I wouldn't put 10000 hours beyond the realm of possibilities before thinking a major rebuild might be required. I'm by no means a Nordhavn expert so some of the real Nordhavn guys here may have a better idea.
I did just look at a large group of Nordhavn's in the 13-15 year old range to see typical engine hours. 2500-5000 seemed the norm. I found a few under 2000 and a few over 5000. Based on that I'd consider anything over 5000 high hours for a Lugger in a Nordhavn. Now survey might show one that age which has been well maintained to have many more hours in it before major issues. But rule of thumb I'd go with 5000 as high based on Nordhavn's on the market. I would not be surprised however to find some still going strong at 10000. I'd compare that to car usage where I start getting concerned around 70,000 miles, have never gone beyond 100,000 but I know many who get up to 200,000 miles out of cars.
