We have 2000 hours on a 17 year old Yanmar
and it runs like a new engine. Our 8 year old Perkins
has only 1000 hours and it's flawless. Neither engine requires any additional oil
between changes. I'd expect both engines to out-live the two of us before requiring a rebuild.
You're comparing 46 boats for sale
, that's ridiculous. We recently replaced a water
which has a larger diesel
than many sailboats, the total cost for replacement was $12000USD. Worrying about a few thousand hours on a diesel
is insignificant in the whole scheme of things, especially when a set of sails
can cost much more.
