    2007 F12 Turbo Aquajet

    2007 Honda F12 Turbo Aquajet.....Is there anything electronically that controls the turbo? The turbo spins easily and is free rolling....the turbo dump valve is moving when I hook up air to the airline that runs to the actuator.....I lubed them up really good with CR526 Marine lubricant. But on the water she won't get over 5 grand rpm. Doesn't feel like the turbo kicks in at all.

    Only 38 hours on machine.

    There are a bunch of potential reasons you might be seeing reduced rpm's. Normally you should see 6000 rpms.

    Check the easy stuff first. Are the spark plugs good? Oil at the right level? Air filter clean?

    Next try to see if the turbo is working correctly. Remove the hose from the waste gate on the turbo, the ski should take off like crazy then throw a code and go into limp mode, meaning it made too much boost.

    If that happens, it's most likely the waste gate solenoid. With the ski off, remove the solenoid and see if you can blow through it. If you can, it's bad. If you can't, with it connected to the ski, start the engine and blow through it, it should be really hard to and you should feel the air slowly escaping in fast pulses.

    If all that passes, report back.

    I'm on the drinking diet. I lost 2 days already.

    And check if you have all the factory air hooses around the turbo.
    The one that goes to the turbo to a T and them to the Solenoid
