[QUOTE="bassboy1, post: 99951, member: 55"] Horsepower is Horsepower. Period. A 2 and 4 stroke of the same hp both have the same ability to turn the same prop. The 2 stroke in your case, is 10 more hp, so even if all else was equal, you have more power there. Also, the 2 stroke is lighter, which is more advantageous. The 4 stroke has more displacement, but as Quack mentioned, the 4 stroke needs that extra displacement to crank out the same power as the two stroke. If both were 70s, you could bet that both of them would be pumping out 70 hp at the prop. The two stroke would still be lighter, and have less displacement, but the power at the prop, where it matters would be the same. Torque might be a little different, and acceleration probably would, but the top end power would equal out. Horsepower is horsepower, no matter how many strokes it has. [/QUOTE]
