What Causes Engine To Smoke When Starting?

Because it is burning oil, an outboard motor produces smoke. Two-stroke engines consume oil on a continuous basis. Four-stroke engines burn oil upon startup mostly as a result of oil remaining in the cylinders, or they burn oil all of the time if there is an oil leak.

When a cold engine is started, it quickly begins to heat up, producing water vapour as a byproduct of the process. When a result, condensation forms in the exhaust system, which eventually converts into steam as the engine’s temperature rises. Once an automobile has gotten up to temperature, the steam quickly disappears.
