Vessel 1 was approaching the Cedar Point Causeway when the depth of the water (unbeknownst to the Operator) becam quite shallow.  The motor intake on Vessel 1 took in mud, blocking the intake so water could not enter the motor.  As a result of the blockage the impeller on Vessel 1 was burnt up, at which time the motor on Vessel 1 also overheated.
