Bob, the retention pin is perpendicular to the prop shaft. It goes through both the eccentric and the prop shaft. Just got mine out just before dinner. I was tapping the “pin” back and forth with a drift set and decided to add some heat. Removed the impeller and after a short heat up period, it started to move considerably faster. The pin must be brass because it’s beat, crooked and junky. Now it’s on to clean up, make a new gasket, lubricate and reassemble!
Keep at it, you’ll get it out.
I believe my eccentric is steel. It’s from my 1940 K3.
