This may seem obvious once explained but why do different rated hp motors with the same block (displacement) have different WOT rpm range? Case in point my evinrude 25 is the same block as a 35 but the rpm range differs from 4500-5500 For the 25 but the 35 is 5200-5800 Rpm. I know that the intake capability has some play but...... still a lil confused.
