Nice job. The Corps of Engineers has a hopper dredge on the west coast called the ESSAYONS. It has two large hp electric motors that run the dredge pumps. The motors are oil filled and operate under water. Duo Cone CAT seals are what keeps the oil in and the water out of the motor. I HATED those seals. You could install them following instruction to the letter…..they may last two hours or four months. Good luck young man!
