    Speedometer is spotty

    So yesterday I took out my 01 seadoo gtx. That was the first time it’s been out in two years. It ran great but sometimes the speedometer would work and sometimes it wouldn’t. I know on the speed sensor the wheel would spin. It seemed like every time the sensor was at the top of the water...

    95 seadoo speedster speed limit problem

    I have a problem with one of my engine. One seem to stop @ 6000 RPM. The other go up to 7000 RPM. I know it might be a MEM problem that could cause this. The speed limit in forward or reverse is 7000 RPM and 3500 RPM in neutral. I can test this by disconnecting the tach wire to the MEM. I like...

    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?
