Try comparing outboards made in the same year by the same manufacturer. That is a reasonable comparison.

Why is it unfair, a lot of those old outboards are still on the lake and polluting this millenium. Any attempt to clean up pollution cause by boat motors would have to start with old two-strokes. Old being anything before 1998 and suspect being anything before 2006.

My boat engine is three star rated, is yours?
CARB'S One Star label identifies engines that meet CARB's 2001 exhaust emission standards. Engines meeting these standards produce 75% fewer emissions than conventional carbureted two-stroke engines. These engines are equivalent to the US EPA's 2006 standards for marine engines.
The Two Star label identifies engines that meet CARB's 2004 exhaust emission standards. Engines meeting these standards produce 20% fewer emissions than One Star (Low Emission) engines.
The Three Star label identifies engines that meet CARB's 2008 exhaust emission standards. Engines meeting these standards produce 65% fewer emissions than One Star (Low Emission) engines.
