OK here it is. I bought a used tractor very low hours in fact 32 on a replacement engine. I didn't do my homework like I should have. Its a 27 HP v twin motor runs great . my problem is its only 724cc equates to 24 hp not 27,. Why is b&s calling this motor a 27 HP ? This is a bs move on their part in my opinion. Engine number is 12 0403 YG 64497
 
My intentions were to remove the engine and use it as a replacement for a ztr I have with a blown cv730 Kohler. Was thinking I was adding HP but looking like I'm not.
 
Ok so that explains a lot. All engine manufactures used to test HP at the highest RPM they could get out of an engine and then tell the general public that was the HP. Now they are not allowed to do that any more. You now get a closer HP rating of the Engine. It is still not exact but much more than before.
 
Guess I'll sale this mower after I fix a couple things on it.I should have looked better before I bought it .

That depends on what year mower you want to put this engine in. If 5 years or less the yes. if older then no.
 
A little green paint and yellow on the deck new blades and replace the bad spindle think I can make a decent profit on my mistake.

The number you sent is not the engine model number, it is an EPA emissions identifying number. The model number will be stamped into a valve cover unless someone has switched them. From your description it is probably a 44 series engine which ran the gauntlet from about 21 hp to 27 according to the sticker and was not unique in this.
