Cant find engine year, please help

I'm obviously new to boating and I want to order some parts for my boat. I've searched and I can't seem to solidify the engine year of my boat.
Is someone able to assist please? I've found some search engine, but even then there's such a discrepancy and I can't find the exact details.

Engine sn: 0M352379

I'm trying to just figure out exactly what kind or generation my engine is and the year it was manufactured. I tried to find the engine plate, but haven't had any luck.

Thanks for any help.

Re: Cant find engine year, please help

Serial number 0M352379 is Model number 4211025PS MERCRUISER 4.3L ALPHA 2 PC, Engine Manufacture Date was 04/05/2002.

Is this engine still in a 2002 bayliner 1850 CB?

Re: Cant find engine year, please help

Thank you very much for the help. It is still in the Bayliner. What does the 2 PC mean? I saw some docs about 2bbl or 4bbl, would that refer to that?

Re: Cant find engine year, please help

Also, are you able to see if it's a 4.3L, 4.3L EFI or 4.3L MPI?

I'm trying to make sure I cover all my bases for future reference and you guys are the pros, so please forgive my ignorance and thank you again for your help

Re: Cant find engine year, please help

It's a carbed engine. Pull the flame arrestor off and look to find out if a 2 or 4 bbl carb.
If you can't tell the differrence between a Carbed, TBI , or MPI engines by looking at it, it kind of puts up a big red flag as to your abilities.

Re: Cant find engine year, please help

I've admitted I'm new to boating mechanics. I've learned all about every vehicle I've ever had by digging and asking questions, which is exactly why I came here.
If you're implying that because I don't know what kind fuel injection system my boat has because it's my first boat that I'm an idiot and shouldn't have a boat (which is how I interpreted your response), then I could no doubt use your same logic and imply you shouldn't be on your pc posting here because you don't understand the bus circuitry of your pc because I'm a computer engineer by trade.
I came asking questions, that's how you learn. I'm sorry I was not born with the infinite knowledge that you clearly have Don.

Re: Cant find engine year, please help

it seems like it's a 2002 4.3 mpi. go to this sight and verify, Mercruiserparts.com them come back and post the results and ask your repair question.

Re: Cant find engine year, please help

And sharkin, I don't have any true repair questions, but thank you. I recently purchased the boat from an elderly couple who have had it garaged for the last 9 years so I'm just trying to get the details figured out before I tune it up.

Thank you all for your help and guidance.
