2 stroke 15hp - Which model is my engine?

[Jabricks]

I just got this second hand engine few days ago without any documentation.

I really have no idea what model is it? What year of manufacturing?

I need to download owner/user manual from the internet but I don't know what engine is it.

A help will be appreciated, thanks.

its an international non US market engine.
I cant help much there.
