OK. . this board is dominated by the Sundancer crowd. . plus a few 48DB owners. I looked around for a 280SS or 290SS thread, and didn't find one. So here we go. . . I know two other 280SS owners on the board. . .anyone else out there? - - - - - - - BTW: I historically have quoted a 46mph (GPS) WOT speed for my 280SS with 5.7's and Alphas at 4600RPM. I saw that speed at Seatrial, and in my first couple of seasons. Last year. . I never saw 46/4600 but it was a full month between splash and when I did a performance run. This year, I splashed and once the engines warmed up I ran pedal to the metal. I saw 4600RPM, and 49.4 MPH. Both directions up and down the bay. I was so happy I just had to call my Mechanic and let him know how good the boat ran!
