The 250 Pro XS has a limiter lower than your tach is showing. We know your not turning that many RPMs. There are a lot of posts on how to drive your boat, not driving through chine walk and the method to bump the trim up on this site. There are more than we could even begin to filter one down. Run a search and check the FAQ section out also. Engine does sound like it might be a fudge high also. Hope you get it all dialed in. BCB
