What Model # Merc Engine do I have

[HPLou]

This is probably a Dum Question, But

With all those Engine # based on Year, I have a hard time to figure what Engines I have.

My Boat has 2 Engines with Alpha One
They are 1989 Merc 4.3 LX
Serial OC534197 and OC454332

What Merc Model are they so I can refer to the Right Manual in the Adult Section ?
How much HP per Engine ?

Also, Please

My Alpha One S/Ns Are OF162054 & OF162055
What Model are They

Your Help will be Very Appreciate

Fun Times,

Here's one, but I've read these are not printable.

Boatinfo - Mercruiser Service Manual nr. 7 - 1983-1993 - GM V6 Engines

And I'm not sure if you'll be able to get this one to work or not,
mercruiser service manual #7 gm v6 1983 - 1993 - Download - 4shared

If not, you may have to ebay the part number for best deal. 90-12410.

Good luck.
