Rule of thumb that I have always been told is down one inch and pitch. So 24x10 2blade=23x8 3 blade.

Oh yeah of course there are variables. I just mean as a rule that is where I start at. The same size 2blade prop from different manufactors will turn different rpms. And as I have found out the highest rpms dont always translate to the best performance.

RE: Prop Size
Actualy the rule of thumb is to go down one size in diameter and up one size in pitch ,
24x10 2 blade would be a 23 x11 or 23 x12 3 blade
There will not be and exact exchange because of the many blade and pitch variiations .
You will most likely need to retune the engine because of the load change. Dont worry about exact RPM's ,tune for the best performance.
