just bought a new/used boat and am not quite sure of the mixture needed. Any help would great thanks.What is the oil/gas ratio for my mercury outboard 2 stroke motor?
It depends how old it is. 50 to 1 is most common on the black colored cases. But if you have a very old Green or White Merc it is possible to be 25 to 1. I have a old 1952 that takes 1/2 pint of 30 weight to a gallon. The motor was made before 2 cycle motor oil was around. Go to Antique outboards group on Yahoo and you can learn allot.What is the oil/gas ratio for my mercury outboard 2 stroke motor?
the ratio is 50- to 1
When you go to buy oil to mix with gas, you have two different sized bottles. Those that makd 40 to one and those that make 50 to one.
40:1 bottles result in a mixure that is 2.5% oil
50:1 bottles result in a mixture that is 2.0% oil.
unless the manufacturer specificially recommends either one, it may not matter. If you want to err on the safe side. use the 40:1.
The worst thing to happen would be to run rich and smoke a little until you replace the tank again.
wer
if i am not mistaken it is 8 ounces of oil to 6 gallons of gas.
