Vessel #1 was operating near the Port Austin breakwall.  Operator stated he came to rest near the break wall to re-adjust the location of a passenger.  Operator said the stern of the Jet Ski then began to sink.  The vessel became submerged and was then towed into shore by a private party.  The vessel was inspected while on the trailer and had no hull or damage to plastic where water could get in the vessel.  The cause of the accident appears to be due to engine malfunction due to the water intake line.
