    Rxp very sluggish no power

    Water tested my ski today
    And it seems very sluggish and will only top 59-62 mph and 7900 revs
    And under heavy throttle the check engine flashes up and the red light comes on
    But if I stick to around 40-45 ish it's fine but with no quick acceleration
    It is smoking quite a lot and 2 sparkplugs are black and one is White
    When I rev it the supercharger pipe has lots of pressure In it
    There are also no codes that have come up
    I have had a new impeller and wear ring so I don't think the problem is there
    This is what my plugs look like after I flushed it on the hose pipe yesterday

    That's not good man. Who did the engine work. I'd consult with the builder. Those plugs look really bad for only having 3-4 hrs on them. Did you put new oil pumps on it? What was the reason for rebuilding

    Not sure about the oil pumps it was rebuilt due to a rod coming through the side of the engine
    I think the old piston rings were put back into 2 of the pistons
    It will be going back to the builder when I get back from holiday

    I doubt I'd be taking it back to that builder for him to do work on it again. I'd be getting my money back and going else where. All new rings should've at least been used in a rebuild. I'm sure some other members will chime in and give there opinion.

    And how could I check the intercooler
