Detroit Diesel. Non Starter

[Divemaster1]

Thank you very enlightening.
as with all engines do not over stress them as with many light weight modern diesels with turbos

Correct.... but let's not forget that this does not only apply to power boats ,,, nor turbo charged engines .... most sailboats have inadequate power to fight a UK tidal stream and strong headwind whilst managing a reasonable passage speed... which together with inaccurate propping often leads to a short & hard runs, often with "less than minimal maintenance" (oil change etc..... why change oil??? ... I hardly use the engine...).... The number of replaced, "worn out" diesel engines in saiboats of less than 20 years of age (below 1000 hrs) that I hear of, is a mystery to me ...
