Did omc have a spec sheet on kr`s& Kc`s? I have a Kc13r and would like to know more about it i want to trace it back to the factory if thats possible.The info tag says it has a oprerating range 5400 to 5800 rpm did they all run that range?

where did all the knowledge go from the guy that did the 2nd Effort V8 offshore boxes?

yes the KC13R had a operating range of 5400 to 5800 rpms but the one that we ran pushed a 27 cleaver 6200
