I have a 1972 85esl72 Johnson outboard motor and I use a 50:1 ratio.
fuel mix for a 1972 ted wiliams 7.5 hp outboard motor
50:1
25:1
99% of the outboard motors need 50:1
The fuel mix is 24:1
well considering the engine type petrol diesel the best outboard motor to get would be a petrol engine as this is easy fuel to come across just don't get any water in the fuel tank as this will cause the engine to cease and that's bad so get a petrol engined outboard motor and petrol hope this helps
