Thanks for posting that bulletin Frank. It was explained to me a few years ago but I’d forgotten it.
Here’s what it looks like in real life. The screw mentioned has been temporarily removed in this photo but the letters ‘AE’ can clearly be seen stamped into the top of the block. This motor is a ’55 Evinrude Big Twin. The Johnson RD should be the same.
Just looking at this photo and the drain hole looks a lot bigger than 5/32″. Since this powerhead hasn’t been installed yet, I better check it.
