Thank you for this information. I’m at work right now but I’ll take a look tomorrow and see what I can see. I had not considered the shaft as being a variable. Now it looks to me as if I do have the correct washers after all and now I know the correct way to install them. It very well may be that in my ignorance I had the washers installed in reverse order.
Now I’m guessing at this, but is there a part number somewhere on the upper lower unit housing that will indicate to me which of those driveshafts is appropriate for my gearcase? I have the short shaft configuration. My outboard is a 1957 but I’m sure it doesn’t have the original lower.
