'84 2.5l OMC Prop question

[Fishergirrl]

We're trying to replace the prop on a used boat with the same engine [MOD EDIT: 2.5l OMC] you have. This guy at the boat store said we need to know the RPM at wide open throttle, but we can't find that anywhere. Can you tell us that info?

Welcome aboard - I've moved you to your own topic instead of hijacking that old dinosaur you dug up.

We can't really tell you a spec of RPM at WOT. Every boat will be a little different, but you can assume somewhere in the 4,600 RPM zone. What is the prop that is currently on your boat?
