They are - most inboard engines are 4-stroke. But as with land vehicles, you can get a smaller engine with 2-stroke (or more horsepower with a smaller engine) so the small engines like some outboards tend to be 2-stroke.

Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
If it is a 2-stroke engine, 2-cycle engine oil is added to the gasoline. If the engine is 4-stroke, regular 30W motor oil is used. To tell if your engine is 2-stroke or 4-stroke, look for a spout where oil is poured into the engine. If there is no spout, then the engine is 2-stroke and 2-cycle oil must be added to the gasoline.
carbon monoxide in 2 stroke engine
you cant turn a 2 stroke into a four stroke. and i don't think you can run diesel in a 2 stroke
2-stroke engines produce much more power than 4-stroke.
In a 2 stroke, every second stroke of the engine is a power stroke. In a 4 stroke, every 4th stroke of the engine is a power stroke. Knowing this, a 2 stroke has double the power as a 4, in the same cc
It is possible to use 4-stroke oil in a 2-stroke engine in an emergency situation. You should not use this oil in the long term as it will damage the engine.
The best way to know if an engine is 2-stroke or 4-stroke, is to look for an oil spout. If the engine has an oil spout where oil has to be poured into, it is a 4-stroke. If the engine has no oil spout and the oil has to be added to the fuel, then it is a 2-stroke.
2 stroke and 2 cycle mean the same thing
yes its a 2 stroke
