1995 Evinrude 200, I have been doing some much needed maintance and wanted to clean and check the recirc valves. I got it torn all the way down to the valves. I tried to use a piece of wire to push them out from the back side with no luck. I thought maybe the nipple check valve might need to come out for it to release but that didnt help either. Tried a small pick to catch the edge to pull it out failed there also. Any ideas what I am doing wrong? The manual says to use the wire, but that didn't work for me. All 6 are stuck in there. Any help would be great.
