Install was a little tougher than it should have been. One of the four holes did not line up very well. Had to over drill a little to make it work. Hook up out of the hole is noticeably better. Still need to be frugal with the throttle when pulling up a skier or tuber (still finds the rev limiter). May have lost a little top end but that has not been confirmed yet due to lack of flat water during the only day I have run it since the install.
