    2004 Seadoo Speedster RPM surging

    240 Merc M2 Top Speeds

    So just curious- what kind of speeds are you getting out of this engine/pump? I have a just purchased 2000 Speedster and I seem to be about 50mph by iPhone GPS. No speedo yet, but I'm betting it will read higher. I thought these boats could hit 60?? Maybe time for a pump refresh?
