Y do I have a different ratio?
 

I am tring to figure out what pitch prop are on the boat. All I know is they were 4 blades and port had a 2 inch hairline in it with a stamp of KME 986// J 655 & J 340. The Starboard prop has KME987// J 340. The ratio is 23 outer- 35 inner on port and 26 outer and 35 inner starboard. They are counter rotating but not a clue why they have different ratio.

Call us when you can. Maybe we can help you to determine where you are and if we can get a better idea where you can go. I think you have 2 inches of pitch differnce?

performance data will help us.
