You can look up the instructions and there will be several that are recommended by the engine manufacture. As long as the engine is kept in the working RPM that prop can be tested. It's a lot of choices. I have seen this chart before and it is something every new pilot should have on there shop wall. The chart is a ball park thing but that's where you start your testing anyway. There is no magic prop or size, one priop does not fit all. The chart is a great start. I'm going to print it out myself and give it to a number of people.
