4 HP Identification

[overthehill]

I recently purchased a 1 cylinder, integrated tank outboard. I can't find the model listed in the parts section. The ID tag on the transom bracket is configured as follows: 4ACMH
6EO S 172741
U

What model do I have?

We only have information on models offered in USA and that model is not, it may be same as US model 4MSHX but not sure.
