I have a 25 hp, four stroke, 2005 mercury bigfoot that sports two identification placards that appear below. I have serched in vain for a model number that is even similar in format to those found in parts microfiche, e.g., 1F25312DN. Note: this may or may not be the model number of my engine. I selected it from a list of 31 model numbers each of which is associated in the microfiche with a 2005, four stroke, 25hp

Anyhow, the task with which I'd like help is determining the model number of this engine. In ordering parts, I can of course, examine the microfiche listed for2005 25 hp four strokes, find one that looks most like mine, and order. but it's something of a crap shoot, and needing a carburetor kit as I do, I'd like to get it exactly right.

The two placards:

Thanks for any assistance. BTW, the little sticker below is from my 2003 15hp four stroke big foot. Such a sticker does not appear, best I can tell, on my 25hp.

Thanks! Your help enabled me to order a carb kit for the engine. How'd you corelate the serial number to model number -- and with respect to the characters at the end of the model number, what's the meaning of "DD"?

I do have the service manual, btw, but thanks for the offer!
