RedactedNarrative: Operator advised he was maneuvering through a shallow area with strong current when his motor failed.  He attempted to restart the motor but the vessel was swept backwards into a stump causing V1 to capsize.  The operator was wearing a PFD and was able to get to the shoreline and walk to a nearby residence for help. V1 was unable to be retrieved until the following day due to the hazardous conditions. Damage to V1 was to the left rear gunwale and 25hp outboard motor.
