Thread: Can anyone identify this 3-barrel throttle body? Possibly marine

I got this throttle body in a box of parts that reportedly came off of a marine BB Chevy. It does not have a hole for a central air cleaner stud. It has two holes near the edge and may have had a flame arrestor type of cleaner.


It is billet and appears to be very well made and has almost no wear. The linkage is progressive and very heavy duty. The IAC looks to be a GM part but I haven't pulled it off yet. It is missing the TPS.


It was in a box with a Delphi type marine ECU and harness. I would like to use this TB on a project with a Holley ECU. It looks entirely usable with a few minor mods and I really don't need to know the manufacturer, but it would be nice to have some info on it.


Several internet image searches have come up empty for me and I thought someone on here might recognize it.

There are no markings on it that I have found, so far.
