Sorry Rockwood, But My system can not find your info, You may want to start a new thread asking about your year, I'm sure one of the other guys might be able to help you out with yours, They are pretty good with the older engines, Or engines made outside of the USA.I have a 65hp mercury just wanted to know if you could tell me the year.
Not sure if I have the right number but I found two.
The one I think it might be is 8343729
Your engine is a 1999 MERCURY 3.0L OFFSHORE EFI 250 XXL EFICould really use help in identifying my Mercury 3.0 liter V6 for part ordering/rebuilding purposes. I purchased with a melted piston.
The data tag was missing from the transom mount, I recovered a number from the block however, 0g900054.
Any help with year and HP rating would be much appreciated!
The competition to this site the marine doctor,sorry Andrew
"How can I find out the year of my motor? It's a 150 Mariner, The motor is grey with the orange strip. Along the strip it has the name Mariner with oil injected printed on side of the cover. Is it the earlier 80's or later 80's model? The serial number is 6494246. I bought it for 1,000 and all 6 cyclinders has a compression of 115-120. Did I get a good deal or not? "
Blue band puts it somewhere between 1972 - 1978 I think.Have a look on the starter bracket there may be a seven digit number there.
