Does stainless change RPM's?

[Wee Hooker]

Thinking about putting a stainless prop on my 30 hp 4 stroke. Same (10) pitch. Generally speaking, should I expect a RPM change with the material change?

(Understanding that there will be other design differences that may weigh in as well.)

Hard to say not knowing what you have now as far as brand and type or what brand and type you're going to. Generally speaking, going from an aluminum prop to a ss prop of the same general design and type will allow you to mount the motor higher. The ss props, generally speaking, will have a more sophisticated design and be more efficient.
