RedactedNarrative: On the 26th of August 2018 at approximately 1200 hours, I received a phone call from operator who said He was operating his vessel(KA2856AA) through the normal channel near Marysville boat ramp on Hillsdale Lake in Miami County Kansas.  He was moving northeast at approximately 20 to 25mph when the lower unit on his motor hit a tree stump.  After hitting the stump his vessel started taking on water.  I told him to tie his vessel to a tree and I would be heading his way.  
  
  I contacted the Jayhawk Marina to request if they could assist subject and his wife.  They said yes and headed that way.  I arrived at the boat ramp at approximately 1220 hours along with Seasonal Park Ranger.  We watched as the Marina vessel towed in the vessel and assisted with getting it loaded onto the trailer.  Once out of the water we could see the lower unit was broke and hanging by the fuel and hydraulic lines.  I took several photographs of the vessel while operator tied up the lower unit.  He then transported it to his storage unit in Hillsdale.  No injuries were reported and the only damage was on the lower unit itself with a very small spot on the fiberglass next to the plug.
  
  Nothing further at this time.
