As I recall I used a cobalt drill bit for the hole in the race. Titanium
might also work. Photos are posted in the album "Aletes SM#240" which may
help clarify the process. I was not concerned about sea water, as it seems
everything in the AutoProp is exposed. Maybe I am missing something?

Hi Mike:

I actually tried to drill into the races but couldn't penetrate the hardened
steel at all. My original plan was to tap some screws into the race and use
a slide hammer to pull the races out of their recess. How were you able to
drill those races?

As I try to visualize your process, didn't this then leave a hole through
the base of the race recess open to sea water on the outside of the prop
hub? Perhaps I am not picturing this correctly. Help me to better

The approach that worked well for me to remove the race was to drill and
3/16" threads through the race and hub, insert short 3/16" bolts from
end until they touched at the interface, then tightened the inner bolt to
push out the race. Next time no need to drill, just insert the inner bolt
push out the race.
