You want around 125 ml of oil to one imperial gallon of fuel. 4 ounces to one gallon gives you 32:1 most people run that but for more power but also more wear you can run less oil say 3.2 gives you 40:1 and i think 2.5 ounces gives you 50:1 but as long as you run good oil you should be fine (hp2 oil is pretty good )
the mixtuer is 40:1 I like to use a 32:1
50.1 ratio
50 to 1
mercury mix 50:1
50/1
model number AE30ELCCE
The owners manual calls for 20:1, however with the improvement in 2 stroke oils since 1980 a 32:1 to 40:1 should be fine.
Ratios32:1 GAS/OIL MIXTURE4 ounces of oil per gallon of gas.
My 75 Johnson is 50:1. If you use a synthetic oil you won't need to worry about it and no more smoke from too much oil
if you are riding it hard all the time mix it at 32 to one if you are just putting mix it at 35 to one you can go 40 0r 45 but you will need to rebild it more often i run my 99 cr at 35 and is great hope this helps
18:100
The ratio is 3:2
