Operator was cruising north on the Mississippi River at about 30 mph.  Operator started to enter Harpers Slough when he noticed he was headed toward a partially submerged log floating.  He cut back on the throttle and attempted to raise the lower unit.  The boat struck the log causing the lower unit to be broken off.  With the lower unit broken off, the boat filled with water and started to sink.  Upon seeing water, Operator had all occupants put on PFDs.  A 911 call was made and a boat was flagged down for assistance.  All occupants were pulled from the water.  There were no injuries.  C. O. and the Harpers Ferry Rescue arrived by boat and towed the submerged boat in to Cottage Road.  The vessel was a 21 foot Mariah Shava, inboard/outboard, with a 5.7 liter Yamaha engine.   Incidents causing the accidents are believed to be high winds, high, rough water conditions and floating debris.
