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.
Who's saying it will hurt them? There is just no need in it now days. They make so much power down low there is very few times they have to be run in the higher RPM range.
