fastrack 18/48 Honda engine question

I just bought a 18/48 fastrack w/Honda engine. My question is: The Honda engine says 18HP on the engine. The model is GVX610. On the Honda website it lists the GVX610 as 16.2HP. It lists the GVX620 as the 18HP engine. What the deal?

Heres the deal....
The gross hp on the engine is 18, the net hp is 16.2
If you go to the site map link on the Honda Engine website http://www.honda-engines.com/sit.htm and look at the engine selections you will see the GVX610 listed as 18hp.
When you go to the GVX610 page it lists net hp with a * next to it and below the specs the * is explained, this is what it says...

* The power rating of the engine indicated in this document is the net power output tested on a production engine for the engine model and measured in accordance with SAE J1349 at 3600 rpm . Mass production engines may vary from this value. Actual power output for the engine installed in the final machine will vary depending on numerous factors, including the operating speed of the engine in application, environmental conditions, maintenance and other variables.
