I took my behemoth on the water this past weekend and noticed the top speed had decreased by 10 MPH. In fact, the entire speed to RPM ratio seemed off. At 5,000 RPM, I generally do about 32-34 MPH. I was pulling at about 28-30 MPH. The top speed never really went past 50 MPH, too. It would normally hit about 62 MPH. I checked the grate for any blockage and saw nothing... only one rail that runs parallel with the hull seemed bent out of shape a little. Could this be the problem?
