Mixing Oil & Gasoline for Two Stroke Outboards

[@jerryq1000]

Wayne, if you're ever without a calibrated mixing container, you can figure out the amount of oil to add by: remembering a gallon is 128 oz. If it's expressed as a ratio (100:1, 50:1, etc.) divide 128 by the ratio; eg. 128/100 = 1.28 oz of oil per gallon. Or, 50:1; 128/50 = 2.56 oz of oil per gallon.

[@WayneTheBoatGuy]

My chances of remembering a number like 128 is about 0 - lol

Ran my 1991 Johnson 9.9 for years on my 14' Duroboat. Before that it ran on my dad's 80 Valco 13'. Good top speed 18 mph and super reliable. Boat got the nickname from some friends of Lil Tug. Due to the one pull nature of the old workhorse, and the fact I have dragged a few disabled boats back to dock with it. Nothing beats the smell of an old two stroke on the water.

My grandfather had a motor like that on "Old Tippy" 10 ft aluminum boat. Thanks for the flashback. I need that measurement cup in my life👍

[@All_A_Guy_Needs]

Wayne another nice video! Love my old 2 stroke outboards. Been running a 1983 15 hp this past week. Lots of fun to be had.

[@theobirkholz]

i used to have to open up google and look up how many ounces per gallon, then open up calculator to figure out how much i needed, until i got one of those mixing containers. super helpful

[@wilco3588]

My first outboard that dad let me play with on an aluminum boat was a three-horse Johnson 1964? Fisherman drive. It wasn't a Powerhouse but it sure was fun!

[@WayneTheBoatGuy]

I bet!

[@wilco3588]

I've been using a version of this since 1987 my first real job was at a sporting goods and Marine store and I worked on a lot of Outboards mostly old they call them vintage now but my boss was very specific on getting the right mixture of oil and fuel. The other thing to do is buy recreational field that doesn't have that alcohol in it. Alcohol is served in a glass with ice and hopefully some proper care for flavor.:-)

[@WayneTheBoatGuy]

Yeah in some areas of the country buying non-ethanol fuel isn't an easy option.

[@Julie-u6r]

love the channel great topics! but please try driving gas tiller outboards the safe way with your left-hand. Emergency lock to lock maneuvers siting in the middle of the seat where the manufactures designed them? made for free use of right hand for fishing, running electronics, etc.

[@WayneTheBoatGuy]

My electric outboards have the tiller in the center - which seems like a better design. Although these are designed to be operated like you say, I often find it easier to be on the other side because I am usually also holding a camera.

[@BurchellAtTheWharf]

I love my ez mix bottle fer my saw

[@BurchellAtTheWharf]

I like the vanilla mix oil from shell, it got the stabilizer in the oil, so if you forget to run it dry at the end of the year, your still good to go

[@BurchellAtTheWharf]

An regardless what the manufacturer recommends I mix atleast 40:1 or stronger (on the oil side)

[@BurchellAtTheWharf]

3:52 I always put the oil in first so then when I ad the gas it helps mix it up. And can use about of the gas to wash a measuring bottle out like this aswell so there is all the oil in the mix😅 but that just might be me, I have made the mistake of to lean on oil and locked up a few motors in my learning experiences

[@WayneTheBoatGuy]

I know lots of people who mix it a bit smoky!

[@BurchellAtTheWharf]

@@WayneTheBoatGuy yess, well it you go high octane and heavy oil, it will last forever. Under oil, you never know when you last runnis

[@WetNets75]

This is one of the few items in my boat that hasn't been stolen once at least. The stabilizer.......I have not been using this summer.......budget cuts. 🙃

[@WetNets75]

Here I am on a Sunday morning, thinking to myself, if the non use of stabilizer has something to do with intermittent fuel delivery interruption, the K. I. S. S. solutions already checked and omitted. It's almost as if something past where the fuel leaves the line, is getting gummed up by ethanol? 🤔

[@wilco3588]

Actually the reason for that bottle is to get your measurement of oil but then you pour gasoline on top of it shake it up and pour it back in to your measured gasoline amount that make sure your oil is mixed and 99.9% of it goes into the mixed fuel can.

Ahhh you're obviously not in North America! We have only had Chinese Hangkai 2 strokes available for the last 20 years or so. No new 2 strokes from Suzuki, Yamaha, Honda or Mercury since about 2006 or so.

[@bcochrane1552]

If you are Canadian and buy gas by the litre. It is a simple conversion. If you buy 20 litres of gas, take the amount of litres and double it, which is 40. Add a zero to the end = 400. Add 400 millilitres of 2 stroke oil to your gas tank. Another example, you buy 14 litres which doubled is 28. Add a zero to the end = 280. Add 280 ml to your gas. This gives you a 50:1 mixture with simple math.

[@WayneTheBoatGuy]

If we wern't mad at France 200 years ago - we'd be metric too!

[@victorsimonsen921]

i mix with a 1 gal can simplifies it. have a small one time use oil bottle that i keep refilling so its just dump in oil then you gal of gas those small mtrs dont use much so it last a few days

[@phillippeacock7255]

That looked quite complicated. By comparison I buy a one litre bottle of 2-stroke oil and it has a 100 ml secondary chamber at the top, which is filled by squeezing the bottle and the oil goes up there by a small pipe. My 50:1 mix just means for 5 litres of petrol, I only need 100 ml of oil, or 200 ml for 10 litres. Maths is easier in metric, but the bottle with the side tube and small chamber makes measuring really easy.

[@stanleybest8833]

Johnson Sea Horse? Elgin, etc? These old 2 strokes have much smoother porting than modern 2 cycles, and that's one reason 2 cycles are disappearing. Fuel stabilizer? I don't use it. I remove the gas and run the last ounce dry.

[@WayneTheBoatGuy]

Someone else said that running these old 2 strokes dry (which I also do because it seems like a good idea) can damage the engine. I haven' t dug into it - just sharing what they said which I found interesting!

[@stanleybest8833]

@@WayneTheBoatGuy No. Clearing the carburetor is harmless. It's momentary and desirable.

[@PapaMav]

I use the clear line on the side of the 2 cycle oil bottel to measure how may onces of oil for 3 gals of gas. Not rocket science. My ratio is actually between 40 and 50 since I use a little more oil than the true 50:1 recommended amount. I use both Stabil and Star Tron Enyzme Treatment (this is what is really for the alcohol in the gas).

[@markallison8108]

I know that you can buy it premixed but it’s a bit pricey.

And some people say the premix can be troublesome - but I have no experience with the premix.

Idk how my step dad would do it without the bottle. I tried a few times. However I would always question it.
