Is this a marine Holley Carb?

[mesquito_creek]

I am trying to go through my project and identify any "non marine" substitutes for safety... Can anyone identify this carb and verify if it is a Marine Application? I see the turned over vent tubes as "marine" but that is all I can figure out. I have got close on the model numbers with Google but not exactly.

HOLLEY
R84023-3
1367

It sits on a Volvo Penta Small Block Chevy motor

Write down all the numbers you can find on the carb. Holley usually puts a number on the air horn. It should say .... "List" followed by a number that starts with an R.

Then go to the web site below and contact the customer support dept. or use the search function to identify the carb.

Good Luck..........
