The California Air Resources Board issued a 15-day notice for its sterndrive inboard catalyst rulemaking, allowing the public an opportunity to comment on the proposal until Aug. 28.
The rule for spark ignited (gas) sterndrive, once implemented, will set exhaust emission standards requiring after-treatment on engines affected by the rule.
The CARB rulemaking is being finalized while an Environmental Protection Agency and CARB-funded salt water engine catalyst test program is being conducted by Southwest Research Institute. The proposed CARB rule will go into effect unless the institute's test program indicates safety or durability issues with sterndrive inboard catalyst engines when operated in salt water.
The proposed rule can be found at www.arb.ca.gov/regact/boatregs/boatregs.htm.

- No crankcase emissions shall be discharged into the ambient atmosphere from 2003 and later spark-ignition inboard and sterndrive engines.
- Production and sale of spark-ignition marine engines that result in noncompliance with the California standard for the model year shall cause an engine manufacturer to be subject to: revocation or suspension of Executive orders for the applicable engine families; enjoinment from any further sales, or distribution, of such noncompliant engine families, in the State of California pursuant to section 43017 of the Health and Safety Code; and all other remedies available under Part 5, Division 26 of the Health and Safety Code.
