Default Advice on getting this off


how do you take off the drive shaft seal /holder on a df175 lower unit? The nut part was corroded and broke. I tried other methods with no luck. Any advice is appreciated.

This unscrews and is not pulled with a puller.

Drill a couple of equally spaced holes and use an adjustable spanner wrench, after soaking the perimeter w/PB Blaster or Kroil. Maybe include a couple pf prayers for good measure. Good luck.

Never dealt with this before. My advice from other pain in the _ss nuts is to...soak with PB Blaster overnight if u can. Take a cold chisel and a hammer and tap it like you are gonna unscrew it. Doesnt look like you could get vice grips on it or a pipe wrench. Hopefully it breaks loose with the chisel and hammer love. If not maybe a little heat from a torch? Emphasis on a LITTLE. Things move differently at 180 vs 80 degrees.

I tried that first. The hex part was slightly corroded and pitted. It quickly broke when trying to take it off. I have the service manual.

If you don't go the spanner route, you might try backing it out the way goneNdoneit said, but use the holes to your advantage. Insert either a hardwood dowel or a steel alignment pin tightly into one of the holes and tap it counterclockwise. Hopefully it'll move.
