i am trying to rebuild my 140 hp mercruiser the boat is a 69, but the parts house said they didn't make a 140 hp in 69, so i have my serial # 2770087 356 84, if anyone knows how to decode it, all help is greatly appreciated.
They go buy the serial # when you order them there really is no year <br /><br />Even in my much newer 3.0 LX there are MANY SMALL CHANGES that require useing the # to get the correct part<br /><br /><br />tommays
That year of manufacture might be the last 2 digits of the boats hull ID number, but not of Mercruisers serial numbers for his engine.<br />The serial number for his engine is 2770087 which is consistant with a 68 or 69 engine. Have no idea what the 356 and 84 came from. Where did you find all those number?<br />Here is the model and SN list from the Merc electronics parts catalog.<br /><br />
thanks for the info, i wonder why he told me they didn't make a 140 hp in 69? oh well,. Those other numbers are stamped right next to the first numbers on the block Don S. well let me give this a try thanks again.
