Could you tell me what pitch and size prop I should be running on this motor? How do measure the pitch on the prop? This engine is on an older model 20' Aquasport with a deep V. I have not computed the speed at WOT yet, but cruising at 4200rpm's it will run around 30mph according to GPS. I was just trying to figure out if that is a little slow. The motor was just re-built 2 seasons ago and has great compression. Thanks in advance for the opinions.
