mixed up black max

[lowrytwins]

I have a black max that I'm not sure what it is. The cowling says its a 150hp. The title says its a 1980 200hp. The serial # is ob314387 which I looked up and I think it said 1988 200hp. I don't know if the powerhead has been changed. But I'm not sure what it is. Does anyone know how I can forsure find out what it is. If you need more info. just let me know. Thanks

The serial number does come up as a 1988 200, may have had cowling changed, no way to say for sure.
