    Are you pulling our leg here? Why does only one motor in the pictures have the line going from the lower main bearing to the upper main bearing? The two motors in the foreground have the spot for the soft plug that has the serial numbers on it but the ones in the background don’t have a spot for those plugs. You are telling us a scenario that seams impossible! You do have everyone’s attention though!

    Looking at some pictures in the Johnson service manual, it appears that early models had the oil line on the other side of the block. Some pictures show the SN plug cavity as you see it here, some pictures (early) show no cavity. Later on, the cavity was moved to the upper cylinder to make room for a fuel pump.

    Sorry, I don’t know the specifics, but it all seems legitimate.
