This is what you want to see because it is letting you know that the engine is being lubricated and you don’t have to worry about any issues there! If you see the blue smoke, we know that we are burning oil. Meaning that it’s burning more fuel than it should be, or the engine is building carbon on the valves. Black Smoke usually comes from a rich burn or carbon build-up.White smoke is usually not a good thing but it doesn’t always necessarily mean there is something to worry about, (we’ll talk about it in a minute!) Note that the gray color can also be part of the white smoke. When the oil is burned it will give off this blueish or even a grayish tint to it. Blue Smoke is an indication that the engine is burning a lot of oil.You can see different variations of the colors, but the main colors are Blue, White, and Black. There are mainly only three different colors of smoke that you will see coming out of the engine. Before that, let’s figure out What Color Is The Smoke & What Does it MeanĮxhaust smoke is the leftover burned fuel and air mixture that comes from a combustion engine. We’ll talk about the reason’s a Four Stroke smokes, here, in a little bit. That is how most two strokes “blow up.” They lose oil and the major components inside rub together until they lock up.Ī Four Stroke, on the other hand, has an oil pan where there is an oil pump that pumps the oil up into the powerhead, ( What is an Outboard Powerhead), which lubricates all of the components without burning the oil and cuts down on the smoke. It would not have lubrication and would fail. Without the oil, the motor would not run. The way the motor operates is by mixing oil into the fuel, either at the carburetors or by injecting it into the reed plates which gets sucked into the crankcase and lubricates the engine. There is no getting around it and there is no real hardcore fix to change this. Is it a 2-Stroke or a 4-Stroke? There are major differences between the two and huge deciding factors that impact why an outboard engine smokes. The key to this portion is understanding what type of engine you have. There are a couple of tricks that can be done to reduce the amount of smoke that an engine burns and here are your best options! What Type of Outboard Do You Have? Four Stroke Engines burn oil at startup mainly because of oil left in the cylinders or all the time with an oil leak. ![]() Two-Stroke Engines burn oil all of the time. Why Does My Outboard Motor Smoke? An Outboard Motor smokes because it is burning oil. Have you ever been at the dock and remember seeing that one guy that smokes out the place? That is, when he turns on his engine it’s like mosquito control coming through and blasting everybody out? Have you ever wondered
