If its running to suit you. good hole shot....planes out good, and is fast enough to suit you just leave it alone man....don't try to fix something thats not broke. As long as your not turning over max reccomended rpm limit at wide open throttle your ok. and I am sure that MS. Slab had it set up where its not going over the limit. Go enjoy the boat and go fishing and quit worrying about it sheeeesh!
