Need Help With 5hp

[CajunBubba]

I just got a 5hp Mariner. I need to purchase a carb kit and impeller, but I cannot match my serial number with any list.
Model#5M
Code#6E3 S
Serial#150077
I need to find a vendor who sells parts for this motor. Does anyone know what year this motor is? I would be most appreciative.

Thanks,
CajunBubba
