I think the problem was they were using the same engines for so many applications.since hp is directly rated to rpms the hp ratings were all over the place.if they would list a engines hp at such and such a rpm like the car companies do it would be fine. but they would take the same emgine run it at 3600 rpms ,and of course it would be say a 12 hp,run it at 1800 rpms and it may only be a six hp.hp goes up as rpm increases,torque gets to a certain point and then falls off as rpm increases.so depending on what amount of torque ,or hp needed they could adapt a single engine to many uses.however the american public has a fetish for hp so they listed the max hp you could get out of an engine,instead of the hp at whatever govered speed you were running at the time at the true applications speed.they werent particularly lying,because you could theoretically get that much hp on test bed,but they were using the numbers as a marketing ploy.
