Re: [OMC-Boats] 1969 buick v6 omc coil

Same boat same issue.

I took my boat out this am and at 3/4 throttle started to sputter and
eventually quit and wouldn't start, had to tow in. Think it might be
the fuel pump (mechanical?) but don't know for sure. I'm gonna try
putting some fuel down the carb to get her started.
