No telling what that carburetor is. The 80486 doesn’t match anything via search through Holley list numbers. 80486 does come back as a classic series 950 but those carbs have contoured bodies with no choke tower. The baseplate also has a vacuum port for non-ported vacuum advance… should not be there on a marine carb so the baseplate has been changed/bowl vent tubes changed. Who really knows??

Can you get a picture of the baseplate with the numbers on the butterflies?
