What WOT engine speed should I be aiming for when selecting a prop pitch?<br /><br />I currently have a Viper 14-3/4" x 19" on a <br />Cape Horn 17 with a WOT engine speed of 5000 rpm. I was expecting 5500 rpm. I checked the throttle linkage, and the carb blades are fully open at maximum throttle setting. Does 5000 rpm sound right, or do I have a underperforming engine? At WOT, the OB sounds very good without any indication of laboring or misfire.<br /><br />Thanks for any input.
