[QUOTE="Johny25, post: 259890, member: 7791"] Well as far as the HP ratings back then....... In 85' they began to rate HP at the prop instead of the flywheel/crank. So the motors prior to that did not produce a true 20hp but they still labeled them as such. This does not factor into labels or serial numbers though. A 20hp in say 84' was really putting out 17-18hp. It is somewhere in the 12-15% less HP at the prop than labeled on the motor back then. [/QUOTE]
