When the CARB (California Air Resources Board) standards get applied to cars and motorcycles, it means more evaporative canisters on crankcase vents and intake systems to reduce VOC vapors into the atmosphere. Perhaps the same for marine diesels as well. One could say that it would make a diesel engine compartment less stinky with diesel fumes and it is also possible that it is a bit cleaner at the exhaust pipe than a 49 state model. Note that particulate standards enforced by CARB have completely eliminated the sale of 2 stroke marine engines in California. It is rather unlikely for Yanmar to offer two separate models of this engine for US sales and it is also possible that due to better engine technology and fuel delivery systems, to say nothing of the higher compression of having a new engine, you may find yourself with improved fuel economy compared to your aging troublesome diesel.

So I have gone for a brand new Yanmar 3YM30AE. It goes in this afternoon. It's pretty and shiny gray and I think I love it. However, I notice on one of the labels that it qualifies with all California emissions requirements. What does that mean in the real world (you know, the part that isn't in California)? I can't help thinking that it means seriously reduced efficiency and power. Running around with a 20-gallon fuel tank, that is a serious consideration. Can the assembled intelligence here give me some insight into what this means?
