Yes it is black & I called the Mercury boat shop & the guy is gonna run my numbers down & see if he can get some jet sizes for me. EDIT & I had called Mikes Carburetor Shop & the lady that answered the phone said it looks like a rochester 2 jet but it ain't (I coulda swore I saw Rochester on it yesterday) & she confirmed that it takes different jets. If the boat shop cannot help I might try to tap em for holley jets & in the meantime start looking for another Rochester carb.
