Information taken from maritimenz.govt.nz/airpollution
Maritime New Zealand have issued new rules applying to recreational boat owners who use their boats in the sea. The rules limit the emission of harmful sulphur oxides (SOx) from fuel use and nitrogen oxides (NOx) from engines. Both of these harm human health and the marine environment.
ENGINES INSTALLED AFTER 1 JANUARY 2023
After 1 January 2023, if you install a new or used engine over 130 kW (174.3 HP) on your boat, it must come with the following documentation:
For a compression-ignition (diesel) engine – an approved Technical File showing the engine’s NOx emissions are within the limits of the IMO Tier II standard. (For further information, including information on Emissions Tiers, visit maritimenz.govt.nz/airpollution)
For a spark-ignition (petrol) engine – a manufacturers’ declaration or certificate of conformity document showing the engine meets one of these regulations:
- Directive 2013/53/EU of the European Parliament and of the Council on recreational craft and personal watercraft, Stage II or higher
- USA EPA Air Pollution Controls 40 CFR Part 1045 – Control of emissions from spark-ignition propulsion marine engines and vessels, Tier 2 or higher
- Australian Product Emissions Standards Rules 2017.
Is your boat’s engine ‘installed’?
An engine is ‘installed’ if the engine, fuel, cooling or exhaust system is an integral part of the boat. For example, an outboard engine fueled from a tank that is part of the structure of the boat would be ‘installed’; while an outboard engine with a portable fuel tank would not be ‘installed.’
FUEL
Using petrol, diesel or gaseous fuel (CNG/LNG/LPG) is fine, and you won’t need to change anything. If your boat uses heavier fuel oils, talk to your fuel supplier to make sure the fuel is MARPOL Annex VI compliant.
