    A rev limiter simply controls engine RPM to about 4200RPM when the system indicates a Low fuel/oil or overheat condition.
    When the condition(s) are met a ground signal from the specific sensor is sent to the LR-54 (depending on model), which in turn connects the gray wire at the CDI to ground. This engages the second timing curve which limits the boat to roughly 4200RPM.

    LOL!!!! I wonder if this makes the other wires nervous? Rev limiter also is reached at MAX RPM set by the CDI box from the factory. I believe 750's are set at 6700 RPM. This prevents the engine from destroying itself if you leave the water (big wave) and don't release the throttle. They can be raised by replacing CDI's from other skis, or some are programmable.
