Vacuum secondaries are not used on boat carburetors.

Sorry Jim, but you are wrong.

I have worked on MANY inboard boat engines with vacuum secondaries.

In fact, my old Malibu Skier (GM 350) has a 4 barrel with vacuum
secondaries.

Please explain...

Oops! I'm so embarrassed. I forgot about Holly style carbs. That
marinemechanic link was a good read. Thanks Gene.

More than just "Holly style" carbs, but you stand corrected. :)

Take care.

Gee, then I guess I didn't have a one of my boats then since my carb
was a Holley 780 CFM with vacuum secondaries.

Those Rochester 4 BBLs that used to be found on Mercruisers are also
vacuum operated to some degree. Vacuum controls how fact the venturi
opens so as to limit lean stumble when they open.

I also had a vacuum advance.
