Re: [OMC-Boats] Rochester 2GC

Thanks Lee,

Ya, found that out when I went to check my manual.  Seems the V6 block on my Explorer is not original.  The serial number suggests it's a '64 vintage block.  Or.... maybe it is original but it's just an older block that was installed.  What's the likelihood of that?    In any case, the intake manifold is a two barrel with a 2GC carb.  Better a 2bbl than a 1, I think!

Here's a webpage  chart you might find helpful that I did quite awhile ago:

OMC used the Rochester  "BC"   single venturi carb on the 1964-1966 150 hp Buicks.
Starting in 1967 the went to the dual venturi 2GC and the engine rating was changed to 155 hp.

Does anyone have a manual that includes shots of a Rochester 2GC carb?  Turns out the orig carb my boat was a 2GC but the manual I ordered for the '65 outdrive reflects only the original 1bbl carb that came with the V6 that year.  Go Figure.

I could use some pics of the throttle linkage.  I've got my carb back together but just want to be sure I have it right.  Seems right but ya never know!

Thanks.
