I put in a new seal kit on the lower unit and had a time with the bearing carrier assembly. Now during the pressure test, it gets to 11 psi and the shaft seals under the water pump are leaking along the drive shaft. I took it apart and checked them, they looked ok, the inner retaining spring had slipped on the inner seal, I reinstalled the spring, cleaned up the shaft some more, and reinstalled the assembly, it still only gets to 10 or 11 pounds. I let it sit for 2 hours and it had bled down to 8 psi. The shaft it still a little rough where the seals ride. I was using alcohol and a greenie to clean it since every other post warns NOT to scratch that shaft. What is my next best move? Do I get sandpaper to try to smooth out that shaft more? Do I need new seals?
