Two-stroke carburettors cause large discharges of substances that are harmful to life in the water and that can spread up the food chain and eventually reach man. Now, several authorities and industry organizations urge all who have such engines to scrap them.
"Please switch to an electric motor, a four-stroke or a modern two-stroke if you want a new motor. They have lower fuel consumption, cleaner exhaust gasses and a lower noise level than the two-stroke carburettors," says Lina Petersson, expert at the Swedish Transport Agency, in a press release.
Despite being banned in new sales since 2007, one in four motor is still a two-stroke carburetor.
The problem is that up to 30 percent of the petrol goes straight through these engines without being incinerated. The gasoline contains hydrocarbons that can lead to, for example, reduced reproduction, cancer and reduced resistance of fish, birds and humans.
The boat return network receives two stroke engines free of charge during 2023.
