I just learned the AM60 is a marinised Alfa Romeo / FIAT 1.9 diesel,

goods.

Modern, small displacement diesels can support a higher RPM. better
than ever. By High RPM were talking up to about a 3200 rpm range. The
bigger displacement engine you have the lower safty range for RPM

Ford learned a costly lesson on it's 6.0L diesel that was put in their
pick up trucks for only a couple years. The supposedly engineering
"masterpiece" has cost Ford dearly in warrenty claims ...
"But it'll turn four grand.."

Yes they were fast rapping, high rev engines, plagued with problems.

They've redesigned and come out with a new engine (again) the 6.4L
which is showing a new promise ... and lower RPM limits.

Not a dis on Ford, but just an observation. BTW, small displacement
Kubota and Yanmar engines are turning over 3500 RPM with extreme
reliability. Don't know why the FNM should't either.
