1997 Mercury 200

My dad purchased a new to him boat after totaling his. It’s a 21ft Triton with a 200 efi that has been converted to a carb. I am looking to find out what it is by the serial numbers and can find nothing on it.
OG 477xxx is the number. I am needing to find out the torque pattern for the heads.

Thanks man. I have new bolts coming. Is there somewhere I can look up this engine with serial number? All my other Mercurys were easily looked up but they are all newer.
