New rules to make the outboard engines used in sports and leisure watercraft safer and cut their pollutant exhaust emissions by 20% got the thumbs up from the European Parliament during plenary in Strasbourg. Parliament backed a European Commission proposal to impose tougher exhaust emission limits on watercraft, to reduce nitrogen oxide and hydrocarbon emissions. Small firms making small engines will have six years to comply, compared with three years for larger ones. Parliament also scrapped potentially misleading names of boat design categories.
