what are the USCG requirements for a marine carburetor

[ron7000]

where can I find the US Coast Guard requirements that specify what a carburetor has to have for operation on a boat?<br /><br />As far as I know, it's just a flame-arresting cover and the vent tubes coming out of the bowls must direct fuel back into the carb throat and not all over. Does anybody know of anything else?

Don't know the specifics but here is what Edelbrock did to make theres USCG compliant...<br />"Cast surfaces are iridited with Teflon-coated shafts and pump arm for maximum protection. Other features include modified bowl venting, specially designed throttle shafts, accelerator pump seal, 3/8" inverted flare fuel inlet fitting, tube in airhorn for fuel pump "

The throttle shafts must be designed not to leak fuel. Holley makes a number of marine carbs including spreadbore models for direct replacement of the Rochestor Quadrajet.<br /><br /> http://www.holley.com/HiOctn/ProdLine/Products/Marine/FMS/FMSC/FMSC.html
