Repower I/O Qs.

[76GMC1500]

kW ratings are identical to horsepower, it's just metric units.

But seriously, if you have 2 engines both turning props at the same speed and are both making the same horsepower, the torque seen at the props is the same, regardless of the torque output of the engine. *If the torque output of one engine was half, it would have to run double the rpm. *In order to spin the prop at the same speed, the transmission reduction ratio would also have to be doubled. *Because the transmission ratio is doubled, the torque output on the prop end is also doubled. *So, the engine that had half the torque at the crank still has the same torque at the prop after going through the reduction gear. *The difference between that 125hp motor and the 5.7L is that the 5.7 would have to be run balls to the wall while the other motor could just chug along.

P.S. I'm trying to be a little controversial to get everybody to think about things. Sure, they're are holes in my logic but there are also points to be made.
