I have read and read all I can about identifying the model for my Mercruiser engine and leg, but I keep coming up with conflicting information. If someone could set me straight on this, I would appreciated it.
First off, photos and identifying numbers. Here is a photo of the leg:
And the serial number of the prop:
And a serial number (A306519) found on the engine:
And a photo of the engine:
I also have another engine marking: "Firing Order: 18436572"
The serial number plate seems to be missing from the engine. It had a major replacement of parts about 5 years ago and may have not been reattached during assembly. But I have two other historical records of the engine serial number, although I cannot verify the authenticity. Since there are conflicts, something is not right. One is from the dealer: "1983 Mercruiser serial number 9077192" and one is on the insurance "1984 Mercruiser Stern Drive 6936610".
I do specifically remember the engine when we bought the boat new around 1984 and the air filter had a "230" sticker on it, subsequently gone.
Looking all these numbers up I get an engine from 1982, 1984 1985 and a leg that could be an MC1 1.50 R/MR Alpha One, but then the database says MR etc.
I give up. Its all too confusing! The photos of the leg make it appear to me an R, MR, Alpha I (1983+) but the DB returns MC-1 (1982).
It is making it very hard when I want to source a prop based upon gear ratios.
