RedactedNarrative: Two men were in 21' Bayliner on Lake Michigan near the Frankfort pierheads when the engine failed, forcing the men to use a trolling motor.  A wave struck teh boat, causing it to roll over.  Operator could get on top of boat with PFD on, and other person on board (also male) was hanging on to the side of the boat.  Operator was able to call 911 and USCG Frankfort responded, found the vessel and rescued the two men.  They were transported to Frankfort, and handed over to EMS and transported to hospital for treatment of hypothermia.  Vessel was salvaged that same night.  Operator said later that the bilge pump had quit and when they tried to power up the engine, it stalled and the vessel flipped over.
  This report came from USCG Section Michigan and did not have names or ages of two men involved.
