  3. CARB Rule Changes Sterndrive/Inboard • CARB Rule Changes for Exhaust Emissions: • New CO standard of 75 g/kW-hr cap for catalyst engines • Allow one engine family or grouping to be averaged in and meet 5 g • fleet average (Must meet 14 g HC + NOx and 150 g CO caps) • Classify jet boats as SD/I • Adopt EPA NTE Zone requirements • Add a hardship relief provision • Require misfire detection in OBD-M starting in 2010 • Initiate a voluntary 5 Star standard • Fix the repower language to not require catalyst engines for repower
