Can someone please help me figure out what year my Mercuiser Engine is? The serial number is A617689 and the drive unit number is OA637671.
Thanks.......any reason why it shows the fuel pump in the upside down position? my pump stands upright with the bowl up top. there seems to be a lot of confusion about this pump and the model years mounting positions. I need to be 100% certain before I order my new pump.0A617689 belongs to a MERCRUISER 140, model number 01402006 which makes it a 1986 year model.

There are/were two designs for the fuel pump...One up one down and searching through the two pump designs in the parts catalog, the one that goes down suggests line modifications would be necessary so either make your own or possibly buy what's available under the facing down pump parts catalog item number 7,Thanks.......any reason why it shows the fuel pump in the upside down position? my pump stands upright with the bowl up top. there seems to be a lot of confusion about this pump and the model years mounting positions.

Then the pump arm will be facing the wrong direction and possibly cause damage to the camshaft.There are/were two designs for the fuel pump...One up one down and searching through the two pump designs in the parts catalog, the one that goes down suggests line modifications would be necessary so either make your own or possibly buy what's available under the facing down pump parts catalog item number 7,

^Usually, you are able to click the Mercuiser part numbers for additional info to the parts you're interested in.
That mentioned, there's usually a scary, to low of a cost to be true/work correctly chance on eBay using the OEM part numbers, https://www.ebay.com/sch/i.html?_nkw=86234A05+&_sacat=0&_from=R40&_trksid=m570.l1313
^ Gotcha to where in further studying, you're correct.Then the pump arm will be facing the wrong direction and possibly cause damage to the camshaft.
