basically the marine carb has the vents turned down-like an upside down J. they also have something on the butterflies-special grooves or sommething. some have provisions for the tube from the fuel pump diaphram failure port to the carb(like my quadrajet). when you have enclosed engine compartment i've been told marine approved components are much more important than open engine setups.

Look at the other jet forum, a thread started Mar 14 on this topic. Here is what I wrote regarding marine carbs
"This info is direct from the CPPerformance catalog. I am sure you can find it at other sources as well.
A marine carb has one principle requirement that makes it different from an automobile carb.
The is a USCG test requirement that if the carb floods, only 0.5 cc of fuel can escape within 30 seconds.
1/2 of a cubic centimeter is not much fuel. Close to the equivalent of a couple of drops from a medicine dropper.
How this requirement is met is three fold.
First, J-tubes dump fuel back into the throat of the carb.
Second, no gasket is used which can saturate with fuel and release vapor.
Third, the butterfly shafts are "grooved" and "slabbed". This prevents fuel that puddles on the throttle plates from seeping past the ends of the throttle shafts. Rather the fuel is channeled into the manifold.
So, there is a difference between the two types. And there is a cost difference. I think a list 9022 (800 DP) can be had for around $500. I haven't bought a standard carb in years, but I'd imagine that a list 3310 or a 4150/800DP for a car is still 300 and up.
If you have a closed engine compartment, in my mind, there is no question. Safety is first. If you ever have a fire or explosion and file an insurance claim, my guess is one of the first things that will be looked at is the carb. I wouldn't want to be on the wrong side of a decision that was made earlier that affects payment on a claim"
More info was posted pertaining to fire safety that is worth reading.
I have replaced my list 9015 marine vac sec 750. If you are interested in this carb, contact me at my profile. The choke assy is removed, a quick change vac sec housing is installed, and I have a new spring pack. Carb was recently looked at by Dave at Fuel Curve. 50 hrs run time.
