    2004 Seadoo Speedster RPM surging

    Hi All, My family purchased a 2004 Seadoo Speedster with Mercury M2 240 engine (2nd gen) last year. We used it all last year without any major issues. First trip out this year everything started fine, but about 20 minutes into our trip (while cruising at about 4K) the rpms started to dip and...

    Seadoo Sportster/Challenger Smoking at start. Mercury Jetdrive 210

    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?
