Reply With QuoteThe solution is very easy: don't go over 75. Problem fixed, maybe a life or two saved. A 21' open bow wasn't built to go that fast, especially one that doesn't handle.
My Boat is running at 80 MPH on GPS at 5100 Rpm with a 28 pictch prop should I change the prop and go smaller or is this good. I also have a problem with the boat anything over 75-80 the boat starts to chine walk and I cant give it any more throttle. The boat is a 21.5 open bow boat with trim tabs and I have tride every diffrent level. Is there any thing I can do to stop this problem. Thanks Dave

How long are your trim tabs, and how far out from the outdrive are they?

What is your current prop?[[ie: Bravo four blade etc.]
