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.

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.

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.

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.
