Chief Engineer for JEMS M/Y was in engine room while V1 was in operation at about 2050 RPM's. Jems M/Y crew were conducting time trials on the engine, when an engine coolant hose split and sprayed hot fluid and coolant onto the Chief Engineer. He sustained 2st and 3nd degree burns to his upper legs, thigh, groin, arms and face area.  USCG responded to the Jems M/Y.  Jems M/Y had lost one engine due to malfunction and was escorted back into Lake Worth Inlet and to Rybovich Spencer Marina.  From here, the Chief Engineer was transported to St. Mary's Medical Center by Palm Beach County Fire Rescue EMS Personnel for treatment.  He was treated and released in the same day.;
