Judging by the age of the fountain(15 -20years old) you may better of just getting a new fountain with a warrenty. That moter is probably a 208-220 volt moter probably around 3000 -4000 gph now thats just a guess and is discontinued and even if you find one its gona run you between 1000 - 1500 dollars. If you rebuild it theres no gurantee it will not blow again and will cost you between 500 - 1000 dollars. I deal with with alot retention ponds w fountains of that size I hate them lol.. Im in ohio as well if you dont have a supplier or no where to look shoot me a pm and ill give you some suppliers in our state and steer you in the right direction.
