Owner of V1 was out on his boat with 2 friends.  After boating for a while, the owner went in and the operator (listed in this report) and occupant continued to boat and stay on the water.  Operator stated after being anchored for a while he started the engine and it began to cut out and then water began pouring in from the stern.  The bilge pump could not keep up and at this point they donned PFD's and swam to the nearest residence on the lake shore.  V1 sank and overturned with only the bottom of the bow sticking up out of the water.

After V1 was recovered, it was determined the drive shaft between the inboard and outboard drive had failed and damaged the rubber boot which allowed water to flood V1.
