He is correct, My 496 sounds built, A little lumpy cam should be noticeable, when at idle. Where is your H.O. runs between 4600-5000 rpm for best HP and I think the 496 runs around 4600 rpm, If you look on the pcm looking at the front of the motor the pcm should be over the passenger side of the motor and mine says H.O. right on it.

Also, the Engine # does not match anything @ http://www.mercurymarine.com/parts-a...parts-catalog/
You might want to get a better look at the engine # and do a search in the link above. There I am sure you can find out what engine spec you have.
