5.7L Merc carb questions

I want to upgrade the carb on my '89 Mach 1 MV2350 Condor 5.7L Mercrusier with Alpha 1 Gen 1 outdrive. Would like knowledge on spacers or upgrade kits for the quadrajet (I think) carb.

Change the intake and the carb. Save weight and add performance.

If you want to change carbs but don't want to change intake and fuel line, you can buy a Holley Marine Q-Jet replacement carb that will bolt right on and go.
