Johnson 4BR77B

[BMJIRL]

My outboard model is 4BR77B Serial No. B48770. It appears the BR refers to "Euro Rope Start". The last B it appears refers to it being assembled in Belgium, and Bruges Belgium is stamped on the badge. I am trying to get some parts, and was assuming I could use diagrams and part numbers for the 4R77B. However, I have noticed some differences between my engine and the 4R77B diagrams. Can anyone indicate where I might find diagrams/ parts numbers for the 4BR77B?

We have no way of comparing European models to USA models, there could be differences in them due to EPA regulations and marketing differences but I don't know what is or could be different.

I understand and appreciate your response. I will try European sources. Kind Regards.
