carb size?

[NautiII]

I have a holley double pumper on my boat. problem is, the horn has been shaved and I would like to know what size holley it is. how can I tell?

I think you can do a couple of things.
1. measure the throttle blades and then jump on the holley site and cross refrence them.
2. On the base plate, it should have the list number on one of the ears.
Maybe others have a better suggestion. I had what I thought was an 850 until I measured the blades.
