Operator was heading south toward Marsh Island Refuge when he noticed his motor making noises and shaking a lot on the transom.  He said he pulled back on the throttle to slow down and before he could stop his motor fell off the transom.  That's when he noticed the transom broke apart and his vessel started taking on water.  Operator then called 911 and we were then notified by our dispatcher.  The bilge pump in Operator's vessel was able to keep the vessel floating until I arrived on scene and tow the vessel back to the launch.  There were no signs of any alcohol or drugs in Operator's vessel.  Operator's vessel is a center console 21' Champion Bay Champ.  Operator was also wearing his PFD.  Operator's motor fell off his vessel because the transom broke apart.
