I am interested in a yacht built by KYDD's Marine of Massapequa, NY. Have very limited info on the boat at moment. Not sure of age but hull number is 4WNCT027G394. Plan is to change the two OMC petrol engines (V-8) - outboard stern drive, model 502APRJUB 987 125 to diesel. Would very much appreciate advice on the engine spec and suggestions on suitable diesel replacement engines. Tried contacting KYDD but no joy so far.<br /><br />Ajigo
