The Cummins 5.9 and 6.7L are rated for 3400 and 3300 rpm in marine applications. Cringe doesn't cause excessive engine wear. Strange how people brag about how tough their diesels are yet they believe running them in their normal operating rpm range will hurt them.
A 6.7 Cummins will spin to 2900 in commercial applications. (Power peak on the ones at work is 2400.)
