"Maintenace costs on a low hour diesel are low, repair costs non-existent. "
Nonsense , oil , antifreeze,filters* must be changed on TIME installed , not just on operating hours.
"Most decent engines will outlast their owners, unless ignored. "
And purchasing a used boat , how does one be sure Da Book was followed for each layup period?
A low end trawler diesel might go 5,000 hours - at 250 hours per year typical, that is 20 years.
"A good diesel will last 20,000 to as much as 50,000 hours without major work. "
Only on industrial sourced engines that work almost 24/7.
Major work on a tug or ferry is an engine removal,
an inframe , cylinders,pistons, main and rod bearings , sometimes cam bearings will usually be done 2 or 3X before 50,000 hours for major work (a machine shop) , rebuild is needed.
Once you get to tankers with 96-104 rpm engines , the life of the engine IS longer.
For most cruisers (usually under 200 hp) with an industrial engine (not a marinized farm implement or light truck engine) over 10,000 hours is a result of BOOK maint, and rare.
It is rare for a yachtie to actually wear out an engine , but to KILL an engine is common and easy to do.
Just walk away for a year or two,
