I'm not the expert, you need to call Tom at the top of the page...BUT that sounds about close to what pitch and diameter most guys run on that style of boat. It seems the bigger issue is your "clicks" of the plate. I'm assuming you have no foot pedal. I've seen your boat, it's beautiful and I'm sure it's making some decent steam. With that much horsepower, I think a foot pedal on your down instead of the clicker, would probably give you the seat of the pants driveability you need with that much power. If you get in trouble and need downpedal you'll never get it quick enough with the handle adjustment. I have one myself, and it's not real convenient. I'm only running a whopping 62 mph or so in mine so it's not real critical. Let's see what some of the other high horsepower V-bottom players have to say regarding their setups.
