Re: engine year

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

Re: engine year

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 />

Re: engine year

cut and paste this longass link below to look up your own parts- print off the pics and the numbers and then go into your dealer with that....Then cross all your fingers and toes as the parts guy tries to type what you highlighted into his computer accurately smacking his gum and picking his nose.......<br />(at least that's how my "live" parts orders go)<br /><br />http://www.dougrussell.com/partscatalog/collections/index.cfm?fuseaction=serials&colid=04&coldesc=140%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20GM%2 0181%20I%2FL4%201968%2D1972
