1976 Mercruiser 233 Rochester Carb Issues

[scottjslc]

I have a 1976 Mercruiser 233 with a Rochester "2 Jet" carb. The numbers on the side of the float bowl are "17056197" and, just below that, "262 5 2". It has an electric choke. I have been replacing the accelerator pump once or twice a season - the rubber "skirt" seal on the pump tears causing the carb to flood. The engine starts and runs wonderfully with a good accel. pump installed. In talking with the parts guy at my local NAPA store (thank goodness they can get the part for me!!), this is apparently not unusual for a Rochester 2BBL.I have several questions:1. Is this actually a 2-barrel carb or a dual-jet single BBL?2. Is there is non-Rochester carb (Holley, Edelbrock, Weber, etc.) or more reliable Rochester that will bolt on and be less troublesome?3. What would be involved in, or is it even possible, to upgrade to a 4BBL for more horsepower. I believe this would require a new intake manifold as well.4. What about electronic fuel injection options (throttle body, I would assume)? Probably "big bucks", but might be an interesting option.I have detailed photos of the carb if they would be helpful - I'd be glad to email them.Any help or thoughts would be greatly appreciated!!
