    2002 Aquatrax won't go faster than 51mph and 5200rpm

    I just bought a used 2002 Aquatrax F12X Turbo. The engine runs great.

    When I take it out on the water it won't go faster than 51mph or rev faster than 5200rpm.

    I checked the oil level. Lubricated the turbo. Took it back out and it goes the same speed.

    Any thoughts?

    Use the NITRO METHOD and check the waste gate solenoid......its only allowing 7lb of boost

    sounds like hose leek in line for turbo wastegate, no pressure. if that fails check for foul plugs.

    Also make sure the wastegate rod is lubercated really good too, sometimes the wastegate valve won't seat all the way

    I checked the wastegate actuator and it moves smoothly when applying 8lbs pressure. Took the solenoid apart, there was a little rust, but nothing was corroded or stuck. I cleaned it up and it still doesn't work. Just out of curiosity, I measured voltage on the connector and it measures 3.0 volts when idling. I ordered a new WGS from dealer. Thought I would find a bunch of these on the Internet. Pretty hard to find unless you go through dealer.
