FWIW, a former director of maintenance at a large NC trucking company told me
the following many years ago.
They expected their fleet of large diesel powered tractor trailer trucks to go
for 400,000 miles when maintained properly. At that mileage, the truck was
pulled from the fleet, the engine was rebuilt and the rebuilt engine was used
for the next 350,000 miles, after which it was scrapped.
Of course the marine environment and limited use of diesel engine on sailboats
(out of slip, into slip, occasional motoring in no wind or for convenience,
etc.) is much different than the long haul trucks. OTOH, if one assumes a long
haul truck averages 40 miles per hour, this comes to 10,000 hours before a
rebuild (or a new motor.) This is likely one source of the 10,000 hour life
number for diesel engine.

be a good idea in 2021? We are running some numbers here and it is basically a
choice between upgrading and replacing. Coquina is 48 years old now and it is
time to do some $$$ upgrades or buy another boat with much of the work done. We
found a used C&C 40 that looks gorgeous below, the interior beats most used
boats of that era. She seems in good shape, but the engine is original with
3,000+ hours. An Atomic 4 per the manual should be rebuilt at 3,000 hours if
FWC, a raw water cooled version would be very lucky to get that far in salt
water. The Yanmar is FWC. I frequently hear that diesels can last 10,000 hours,
but then again a significant number of boats from that era are for sale with
new engines.Also re the rod rigging – the mast is out for the winter. With the
rigging easily accessed, what would the cost be of a rigging inspection to
assure that the rod is still good.Thanks! Joe Della BarbaCoquina C&C 35 MK
