Not sure of hours but this motor has been really good to me. This weekend hit a piece of wood coming across the river. No change in rpms. Next spot jump I noticed a hollow sound but running. This morning, running to first spot about half way there, sounded like it dropped out of power band rpms up but only idle speed. I have done zero testing, it poured rain here all day, as I'm typing power is out. At weigh-in someone mentioned possible reed plate?? Thanks for any input.
