Hi all - trying to remove the impeller from the shaft of my Oberdorfer raw water pump. It is wiggling around on there so it’s not corroded or anything, but I just can’t get it off. Tried soap for some lube and it made no difference. Ideas?

I had that problem. I took a 2X4 wood, drilled a 5/8" hole in it and placed the shaft with impeller in it and using a wooden dowel I hammered it out. To keep it from freezing again I put lanolin on the shaft.
I suspect you have not used your engine for many months. The dried salt water causes these problems.
