Fuel mix ratio for outboards

this depends on the make and year and horsepower .older models used ratio of 25-1 and newer ones used a ratio of 50-1. some have even went to 100-1 but if I had to error I'd rather have too much oil than not enough to lub the cylinder wall and piston. oil only makes them smoke more

I need to know the ratio of a gas and oil mix for a 1999 yamaha outboard motor 90 horse power already broke in...

I'am amazed it doesn't have an oil premix that gives it auto oil mix.If it doesn't than the mixture is 50/1.That is fuel /oil ratio.e.g. 50 litres of fuel to 1 litre of oil.Hope this helps

What type of petrol is needed for a yamaha outboard motor horsepower 8?

reg unleaded gas.

You haven't specified as to its year of manufacture, so if its older, as in a 2 stroke, it'll be a mix of gas and outboard oil.

If its a newer model, a 4 stroke, it'll be injected(Gas and oil seperate)

If you are totally unsure, Consult your owners manual and if you have none, then any Yamaha dealer can use the serial # off the motor to establish any specs on it for you.

Happy boating.
