Etec VS Yammi tug o war

[Stinky_Hooker]

All else being equal a two stroke is about 50% more powerful than a four of the same displacement. The disadvantage of a two is they dont last as long. they run harder, hence shorter lifespan.

This is why a four stroke outboard is so much heavier. They have to displace more cc's in order to produce the same power as a two stroke rated at the same HP.
