Re: Tomos - Koper 4 Hp Year ?
I found one reference on the web to that model, and the date mentioned was 1989. Apparently, it's made in Yugoslavia. A google search for Tomos Traveler Outboard will find the site.
The discussion thread was from 2004, and mentions a UK source for information and parts...but just a phone number.
I could not find any US supplier.
Apparently you have a rarity here in the US, but they appear to be fairly common in the UK.
