Again, you are confused, two stroke can be sold in California, the requirment is that all engines sold meet the CARB requirments and they do, both two and four stroke.
The modern DFI two strokes do consume a small amount of oil but so do four strokes. It is called an oil/filter change. Modern DFI Merc, Evinrdue etc two stroke outboards are the cleanest and most efficinet outboard engines made, they are as efficinet and EPA compliant as their four stroke cousins.
Small outboards do not lend themselves to DFI technologies, that is why most small outboards that are CARB compliant are four stroke, once above the 40i/60 horse range the DFI two stroke engines are very popular and very CARB compliant and very Legal.
