mercruiser serial number help

[manyolkars]

Hi, I have spent many hours searching the internet for info to identify my 4 cyl Mercruiser engines. Somebody please point me to the right website. Thanks My first engine is missing the riveted tag at the back of the engine. The serial number stamped on the pad behind the fuel pump is V04024CN. this block has a GM casting number 3937746. The other engine has the riveted tag with number 4651392 and on the block behind the fuel pump is serial number MII257RA. This block was Hecho en Mexico with a cast number 27700 with 87 stamped at the end of 27700. I appreciate any help!

Call mercury marine and select the option that says sterndrive questions on their automated answering system. Tech will answer and give them the number off the pad by the fuel pump. From there they will be able to tell you what you have. Also, if you have one of the transom assemblies or drives, the serial number off one of those links them to all the numbers on the boat, ie engine, transom assembly outdrive. This has worked for me on occasion for setups dating back to the early 80's. They even told me the original owner's name. They were closed today as I was trying to ID some drives myself. Good luck

If your engines came out of the Belgian factory for Mercruiser & Mercury, then contacting Mercury Marine in the U.S is useless. Try also contacting the European Branch through " Marinepower".

You can interact directly.
