Well after I completed the stereo install last weekend, I installed a Cobra The Edge Stainless Hydrofoil on the engine. I've used these on other boats and always had great results so I thought I would give it a shot. I have the Express Tube package that sits really low in the back and while I had no trouble getting on plane, pulling tubes or top end, I really couldn't trim the engine up much without the boat starting to porpoise. After installation, the boat rides a bit higher in the back and doesn't porpoise on the top end and stays on plane at a much lower speed. I might have lost a mph or two on top end, but everything else about it works like a champ. I know there are folks that don't like hydrofoils, I'm just not one of them!!
