hmmm 50 to 1 is 5o parts petrol to 1 part oil, so thats 2ml oil to 100ml petrol, so 1ltr =1000ml =20ml oil per 1 ltr, so 5x20ml is 100ml of oil per 5ltr for 50 to 1

Unless your outboard pre-dates the early 70's it was designed to run on unleaded fuel. There is no catalytic converter on your outboard so any petrol could be used. Unleaded is cheapest.
The oil required should be TCW-3 standard. Just about any marine 2 stroke is labeled as this standard.
As Chris has described, 1 litre = 1000ml so 5 litre is 5000ml. 5000 divide by 50 = 100ml. So 100ml to every 5l of unleaded petrol.

sorry kev got confused with 25-1 which is my old seagulls mix. 100ml is correct for 5 litres. chris and tomcat are right

The bottle you buy the oil in will usually have markings down the side for measuring out the oil!
