The rev limiter is 6400 on the XS. I like to prop so I'm right at the limit in cool weather. This gives you the most RPM in all temps. You could talk to Dewald about tweaking those props one more time to get another 200 RPM. Not sure if it would help, though, as your prop slip is fantastic. I'm at 10%.

Still loving the Dewald 5-blades. I bought Shaun Torrente's laser setup tool and started experimenting with propshaft height. I knew I was on the right track after going up to 1-5/8" and saw the best speed my wife and I have seen together. So, I tried 1-3/4" and got the boat out today by myself. Water pressure was still good at 15 psi and there was no difference in handling. It was a super calm day, but it recorded a new best top speed just a tick under 110. I know with some more chop, it will hit 110.
