    Engine Surges below 5K rpms

    Finally got out on the water for a good amount of time today and noticed that below 5K rpms the engine surges +-200 rpms almost like it is hitting a wake only in calm water. I checked the TPS with candoo and it seems fine. Doesnt have any flat spots. Any ideas on what else it could be?

    Thanks for the input.

    Bone stock. Just bought it less than a month ago. Ran it on candoo again and no faults, everything checks out but what is the intake pressure supposed to be when the engine is off and when it is at idle?

    I guess I will pick up a fuel pressure gauge and check my fuel pressure next.

    Thanks

    It's very common.
    I've tried changing plugs and it still did it.
    It's like the ski pulses up a little.
    Nothing to be worried about.
