I was changing the LU oil today and had a lot of water come out when I drained it. I pulled the prop and found some fireline rapped around the shaft by the seal. I pulled the line out and flushed the gearcase out with diesel and ran air through it for about 1/2 hour and re-serviced it. I'm going to try it tomorrow and drain again and check for water. How hard is it to reseal the LU, especially the seal by the propeller?
