Re: overpropped vs underpropped
....Having just replaced my three blade fixed with a four blade feathering. I find that I can only get to 2900rpm with the max WOT at 3200. ....
This is confusing. If your new feathering prop won't allow you to get to max rpm under load, then it needs to be adjusted. If you're uncomfortable at any given speed, just pull the throttle back. But it should be able to get to max rpm.
