Deitrich Diesel Marine Repair

I STARTER MY COMPANY IN 2018 AFTER RETIRING FROM CATEPILLER AS A FIELD SERVICE MECHANIC FOR 24 YEARS.  I WORKED IN THE MARINE AND INDUSTRIAL FIELD EXTENSIVELY PERFORMING REBUILDING OF PROPULSION ENGINES, AND REDUCTION GEAR REPAIRS IN THE MARINE FIELD. IN THE INDUSTRIAL FIELD I DID THE SAME REPAIRS ON GENERATORS. I HAVE AN ACTIVE ACCOUNT AT FOLEY CATERPILLER IN NEW JERSEY BUT WOULD LIKE TO HAVE ANOTHER SOURCE FOR ENGINE PARTS AND SALES. ALSO LOOKING FOR A SOURCE TO PURCHASE USED MARINE ENGINES FOR REPOWERS ON TUGS. PRESENTLY I AM LOOKING FOR A PAIR OF COMPLETE RUNNING TAKE OUT FOR A TUG. I AM LOOKING FOR CAT 3412 MARINE ENGINES THAT PREFERABLY THAT ARE 650 HP, OR 720 HP RATINGS, SERIAL NUMBER 9HP, ARRANGEMENT NUMBER 1833882. IF YOR COMPANY HAS A PAIR OF THESE ENGINES I WOULD LIKE TO DISCUSS A PURCHASE. THANK YOU GEORGE DEITRICH.
