    How much compression on a spark?

    I would like to know about how many PSI should a Sea Doo Spark have when doing a compression test?

    There's no mentioning of that in the shop manual, in the cylinder head section they describe a leak down test procedure to determine the engine wear. It's a more exact and reliable method as far as I know, but requires specific equipment.


    I think the best you could do with a regular compression meter, is to make sure all three cylinders are reasonable equal in measured compression, and I think you are supposed to do it with wide open throttle for a proper reading.
