Hello. My name is ***** ***** the careburetor I would go with. Thses are the carbs that Mercruiser went to in the later models of the carbureted engines. Go with the 750 cfm. Here is a link to Edlebrock 1410 marine carburetors. These will adapt to your engine with no issues.http://www.edelbrock.com/automotive/mc/carburetors/marine.shtml Post back with questions.

Mine are not electric choke.
Expert:  Tan replied 6 months ago.
All you have to do is run a ignition wire from the ignition coil to the choke and a ground to the engine. Other wise you will have to go back with the Rochester Quadrajet.

Is the Edlebrock that much better
Expert:  Tan replied 6 months ago.
I think so. They don't have the hesitation issues or leak down problems the Q jets have. So you get better accelration and quicker starts.

Do they have the same footprint -- do they bolt on without adapters
Customer: replied 6 months ago.
and the linkage matches up?
Expert:  Tan replied 6 months ago.
You will have to change the base gasket. The bolt pattern is the same.
Expert:  Tan replied 6 months ago.
You might have to make some minor adjustments.
