"Slip is never a negative number, and will range from 5% on a light cat to 25% on a heavy workboat. Most hi performance applications will be between 7 and 12 percent."

25% - 30% slip at Cruise and Wide Open Throttle (WOT) puts you into the work boat (Barge) category.

The 3.6L V6 models use a 2.29:1 ratio. (I made the assumption you have the 3.6L w/2.29 ratio when calculating the slip)
The 4.0L V6 models use a 2.08:1 ratio. (if you have the 4.0L with the 2.08 ratio, slip numbers increase to 33% and 36%)


Your prop is a 17P
