So stupid.... but oh well... lol

Where did you find this information? Can you share a link to it?

Every place I have looked comes up as a '97 carb engine including the Mercury site.http://www.mercurymarine.com/parts-a...parts-catalog/
Launch catalog-enter serial number OK282859 -select "engine" catalog-click down arrow in drop box above parts list. You will then see all the catagories of parts for that engine including carburetor.

A cover that says 7.4/Bravo is a non-Mag.
Mags have aluminum GM hi rise intakes, and MOST non-Mags have cast iron low rise intakes. NO MAGS have cast iron intakes. If a magnet sticks to it, it is DEFINITELY NOT A MAG. If the magnet falls off, then it MIGHT be a Mag, but not necessarily.

If you put in my serial # it comes up with mag heads and bravo heads in its parts list so that why I'm confused

Hey Spooln, you posted this same question on another forum, which I looked up for you. However the serial number you posted there was ok282585, which is a carbed gen VI 7.4L. Which number is correct? The number you posted here, ok282859 is indeed a TBI 7.4L.

bobl 585 is correct one. I know its a Gen VI 7.4l Carb wanted to know what heads are on it. I get different listings for heads might be rec. or peanut heads

Simple. After you type in the serial number the next screen will come up saying it's a "Gen6 7.4L Bravo". If it were a mag it would say "Gen6 454 Magnum Bravo". Diagram is used for both models. In the list it shows 2 listings for heads. One says 454 Magnum and the other 7.4L Bravo. Beings this serial number comes up as a 7.4L Bravo then it would be the heads listing which says 7.4L Bravo after it. By the way both serial numbers that Bob L listed come up as the same engine, model 474B110KS carb engine.

Bob, I come up with both of these serial numbers being the same engine model, 474B110KS which is a carb engine. Sure your not confusing it with TB5 which is Thunderbolt 5 Ignition? Can you post a link to where you seen this?

Oops, my bad. You are correct they are both the same carbed engine. I'm a Merc dealer and looked it up on product history. I just had TBI on the brain after seeing the conflicting serial numbers and other post about TBI. But to answer Spooln's question that is definitely a peanut port engine. It used a GenVI roller cam short block, but the peanut port heads as opposed to the Vortec heads on 1998 and later 7.4L.
