After draining my lower unit for lube change, I stupidly saw the other bolt head on the right Bottom.(From the rear view of the engine. I thought I had not got "both" drain plugs and started to turn this bolt. I immediately stopped when I realized what I was doing. I had turned approx. a 1/4 turn. What is this bolt head for and how bad did I screw this up?
Thanks,
Ken
