    1. Anything on the impeller from a few blades of seagrass to a plastic bag or 2.Stripped drive shaft..are the common areas.

    slower lower Delaware. And have a cottage on finger lake in upstate NY.
    Also check your impeller to wearring clearance. It should be less than .018 inches. Anything greater than that and you'll have cavitation issues.
    Any damage to the impeller will also cause cavitation. The impellers edges should be clean without Nick's or sudden bends.
