I believe this on a V6 block would indicate a 135 hp - maybe a 2.0 lt??

I've never seen "AA", but I don't mess with 135s either. Does it have a serial number?
AA usually means 150 2.5 carb non xr6
Sn 0g654194 thanks
Serial comes as xr-6 MagIII, but parts list show 2.0 pistons. Something don't add up. Does it have a 4 1/4 or 4 3/4 lower unit?
"Something don't add up" I intend to buy this PH which is offered as a 2.5lt 150hp, to complete a spare fishing motor - I started poking around on SN # and saw the 2.0 lt piston info also - got seller to send me block stamping letters (photo above) - I do not want a 2.0lt engine nor a 135 hp so trying to confirm what this is.
Lower diameter - easily swapped so I don't want to depend on that for ID.
I think id buy some head gaskets and pull a head to be sure. These Mercs are confusing to say the least
I bought a 150 a few years ago. Thought for sure it was a 2.5. I was wrong, turned out to be a 2.0. LakeFever is right. Only way to be sure is pull head.
The 2.0 had 8141 rods in it too
My 1995 135 2.0 has the AA stamp on block also...i always thought or was told that it was a 2.5 block with 2.0 sleeves and pistons.
Maybe its one of those fat blocks?
I've seen the AA stamped as both a 150 2.5 and a 150 2.0 (Fat Block)... pretty much have to yank a head to know for sure...
pretty sure tha only 2.5 150's were either XR6 or efi till tha 2.0 liter went away...…...
From what I thought I saw they made 2.0 lt up thur 2000 ?
According to Mercury engine serial number states, 1997 MERCURY 150XL 2.0L Carb Offshore
