Over propping is simply the installation of a fixed pitch prop that will not let the engine achieve the manufactures rated max RPM range on that specific platform.

My wife like most woman is very perceptive, if your wife has a "feeling" perhaps she should be in as an adviser. Men tend to be.... how do I say this .... hardheaded and stubborn as to their beliefs.
I can dig up evidence to support most any belief, the reliability or accuracy is always what needs to be questioned.
I can only offer the "facts" as to how they effect me but I am not a fan of gross
over propping weather in an aircraft or a boat.

diesels are going to be fine with a small amount over propping when not run on the pins for long periods of time, this is my educated opinion. Turbos will get into high EGT's in this condition as any truck driver can tell you.
