Sorry People, I need to get to Level 4. Any 2 stroke outboard will run just fine on a (24 to 1) mix ratio prior to 1965, (if you do not have your owners manual.).......(50 to 1 TCW III ) 1965 and up, EXCLUDING direct injection 2 strokes that require an added synthetic detergents to comply with EPA and manufacturers warranty requirements. Some will argue that, since the quality up grade of the TCW oils, this will allow you to use a 50 to 1 mix in engines prior to 65. This is a false assumption. Get a owners manual.

Nearly all Johnson and Evinrudes from the mid-60's on are a 50:1 ratio. That means a pint of oil to 6 gallons of gas. Mercs of the same time period are often 40:1, pint to 5 gallons. The tank that came with the engine will usually have the proper ratio printed on it. Older Johnsons and Evinrudes that have a dual-hose set-up were 25:1 or a quart of oil to 6 gallons of gas. I have and '85 Johnson 120 HP that gets the 50:1 mix in the tank at the start of the year until I know the injection system is working. Also mix gas this time of year to ensure proper oiling here in northern MN.

That would depend on the manufacturer and model number. There are a variety of mixtures that all sound pretty much the same. They are not. If you get the mixture wrong at best you will foul the spark plug with oil and be stranded on the water. At worst you will burn up the engine and be stranded on the water. Send an e-mail to the Manufacturer. All of them have web-sites and customer service.

I assume your talking about a pre oil injection engine? If the engine sticker is missing try 25:1. After a few runs check the plug. If its clean 25:1's OK, if its dirty try 40:1.
Any leaner than 50:1 will lead to major problems. I used to run a little Merc on approx 30:1 which was OK for that engine which lasted for years but it is better to stick to manufacturers recomendation.

The ratio will vary from one engine to another.
You should probably begin by inspecting the engine itself, to see if there is a label... next check the handbook.... or the maker's website.

Depending on year and model.It could be as high as 25:1 to ,like my '89 johnson , 100:1 . Check with your local marina.They'll steer you in the right direction.
