Thanks a lot for the reply.
Where i can find the model number ? The only i know is the serial number.

Post the serial number. Older models had a two part serial number, the first part being the relevant model number The numbers should be on a plate on the transom bracket

Do you know the age.

Generally anything from 1964 onwards will run on 50:1. I think all 6 hp models are after that year. ( except for a couple from the 1920s)

The s/n: 6203B17031 I dont know about the age.
Is there a spesific kind of oil?

[Vic.S]

6203 is the model number. It makes it a 1972 model

50:1 fuel mix then using a TCW3 2 stroke outboard engine oil

That's near enough 1 pint in 6 gallons

more precisely

2.56 fluid ounces per US Gallon

3.2 fluid ounces per UK (Imperial ) Gallon

20mls per litre anywhere in the world except the USA

2% if you are a mathematician
