That's why it's a range..... 4600 lean and mean 4200 with the whole fam
damily.

But assume 4600 is max at leanest config, so if you prop it lighter, watch
the tach and don't exceed.

So my new 21" pitch -- me alone, WOT , semi-flat water trimed right, 4300 RPM --
the prop is no good? Too much strain on the engine?

(I may have 14.5x21" prop for sale soon)
