[QUOTE="FuzzyGrub, post: 213596, member: 3438"] I'm not saying the gps is lieing. But, negative slip is not possible. So, your rpms have to be over 6K, and/or prop has cupping, that would make it act like it has more pitch, etc. PS: I don't think there is a rev limiter. I haven't come across that in the Merc service manual, anyway. If it did, than it would kick in around 200 rpms above max, so 6200rpm. That would make best case for your numbers, which would equal zero slip. [/QUOTE]
