RedactedNarrative: Vessel 1, with operator 1 and victim 2, onboard was on Lake Erie when the boat took on a large amount of water causing all but about four feet of the bow to go under water.  Operator 1, and victim 2, were able to put on PFD's, and were in the water for around 24 hours with a water temperature of 60 degrees before vessel was located with no victims.  Operator 1 was located about 24 hours after the vessel and victim 2, was located about 48 hours after the vessel was located.  Both operator 1 and victim 2, were wearing PFD's but were found deceased due to exposure.  The examination of the vessel and investigation found that vessel 1, had the engine block shift for unknown reasons due to not being bolted to the hull and secured.  The shifting of the motor caused the rubber seal/bellow to detach from the transom and outdrive allowing a large amount of water to quickly enter vessel 1.  Overall age and poor condition of the vessel was a factor in incident.  Operator 1 cause of death was exposure to the elements, hypothermia with acute methamphetamines' intoxication.  Operator 1's, drug use was found by the coroner as a result of toxicology test.  No information was found during the investigation to indicate that drug use was involved other then a past history of prior drug use by operator 1.  Victim 2, cause death was ruled to be hypothermia due to exposure because of water emersion in Lake Erie.
