I'm not trolling here, or needlessly fuelling the debate, I'm genuinely curious as to how you achieve the low weights of 2s with a 4s
They are still about 50lbs heavier than an etec for engines I've looked at (150-250hp)
However, as I said previously, they have clearly been spending their money on weight reduction and better materials must come into play.
However, being a cynical git, I do wonder how thin all the bits are on that yam mentioned.
Re 4 strokes being more complex..... with power steering, auto trim, fancy oil injection systems and direct injection with high pressure fuel pumps, are they still more complex?. Not a single 4 stroke has any of that just now.
In terms of moving parts, ofcourse the 4 stroke has more, but we can't call a timing belt or chain complex in this day and age surely. It is a basic mechanical system that is taken for granted in our cars, why not Outboards?. That g2 is just as complex but in a different way. The days of basic engines are over for most.
