Pay attention boaties, anglers, and water-sports enthusiasts! If you haven’t heard already, big changes to laws about outboard motors will take effect on July 1, 2019.
That is because the new Outboard Emissions Law was passed last July 2018.
This law sets new emission standards for small outboard motors with power of up to 19kW, including all types of marine engine.
With the new emission standards, boats with carburettor-based outboard engines that have high emissions are no longer allowed to operate.
If you own one of these boats, then it’s time get a new outboard engine that’s compliant with the outboard emissions law.
Which outboard engine should you buy?
The answer is fairly simple, you should aim for a model with direct fuel injection (DFI) capability and you can choose either a two-stroke outboard or a four-stroke outboard engine.
Modern outboard engines with this technology have low emissions, more economical, and are quieter compared to old outboard motors.
Two-stroke Outboard Engines
Although most high-emission outboard engines that will be banned by the new law are two-stroke, this doesn’t mean that you can’t buy a compliant two-stroke outboard engine.
In fact, the latest generation of two-stroke engines has direct fuel injection capabilities that will result in lower emissions. They are more environment-friendly compared to the old two-stroke carburettor outboards.
Aside from having clean engines and being compliant to the new outboard emission standards, these newer set of two-stroke outboards are also lightweight that provide better fuel efficiency and improved acceleration.
If you want to purchase a new two-stroke outboard motor, here are some of the good 2019 models for you to choose from.
Evinrude E-Tec Range
Distributed by Telwater, Evinrude is a Canadian outboard brand and the only maker to achieve environmental certification in Australia.
Its E-Tec range of outboard motors is equipped with direct fuel injection technology.
A good choice of model is the popular Evinrude G2, which has outboards with power from 25hp to 300hp. There’s also the Evinrude G1, a mid-range model powered by a 1.7L V4 engine with 115hp or 130hp output options.
Tohatsu TLDI Series
This Japanese brand is quietly gaining recognition among boaties because of its quality outboard motors.
One of its best offerings, the two-stroke low-pressure direct injection (TLDI) series, can also be an option for your next two-stroke outboard that will comply with the new emission law.
This series has models of 40hp, 50hp, 90hp, and 115hp output options. These models have efficiencies similar to four-stroke motors and also have better fuel economy.
Mercury Optimax Range
Mercury Marine outboards are some of the most popular boat engines in Australia.
The company responded to the demand for low-emission engines by producing DFI two-stroke outboard motors of their own, the Optimax two-stroke outboard ranges. The first one is the Standard Optimax range, with models available in 200hp, 225hp, and 250 hp options.
The second range is the ProXS Optimax with high-performance models ranging from 150hp to 250hp output.
Four-stroke Outboard Engines
If you want to do better than just to comply with changes to laws about outboard motors, then you should buy a four-stroke outboard motor.
It emits fewer pollutants, it’s more fuel efficient, and will last longer than two-stroke outboards.
Four-strokes have the newest technologies in outboard engines today, that’s why it’s the more popular type of engine among consumers.
Almost every manufacturer has ranges of four-stroke outboards to boast, but below are the best ones that you can buy in Australia.
Honda V6 Outboards
The first to develop a range of outboard engines with low emissions, Honda continues to supply boat enthusiasts with durable and environment-friendly motors.
The Japanese brand offers a range of high power four-stroke outboard motors: BF200, BF225, and BF250.
All these models are equipped with Programmed Fuel Injection (PFI), a computer-accurate fuel injection system for better fuel efficiency.
Honda BF225 and BF250 V6 Outboards are also fitted with Variable Valve Timing and Lift Electronic Control (VTEC) system, that provides more power to the engines.
Yamaha High HP Four-Stroke
Yamaha is the largest outboard manufacturer from Japan and has some of the best low-emission high power outboard motors in Australia.
Its range of four-stroke outboard engines consists of models with 115hp to 425hp output. Yamaha’s most powerful four-stroke engine, the all-new 5.6-litre V8 425 XTO outboard, is also its most technologically advanced outboard product.
The brand also has a range of mid-range models to choose from depending on your needs. Some notable models include the lightweight outboards Yamaha F60 and F70; and the newest additions to the range, F25 and F90.
Suzuki High-Performance Outboards
Compact outboards with remarkable performance and fuel economy; these are the traits that separate Suzuki outboards from the others.
Suzuki’ V6 high-performance four-stroke outboards range has models with 100hp to 350hp output options.
The flagship models, Suzuki DF350A and DF325A, are given a new hydrodynamic gear case design that will help reduce the drag by up to 36% compared to the old models.
Which should you buy?
Buying either a two-stroke outboard with DFI technology or a four-stroke outboard engine will help you comply with the changes to laws about outboard motors.
Both are cleaner engines compared to the old carburette motors and will definitely meet the new emission standards.
If you’re absolutely asking which one is better, we’d say that it depends on your preference and priority.
That is because both types of low-emission outboard motors also have disadvantages that you will have to deal with, whichever you decide to buy.
For example, four-stroke outboards are more durable compared to two-stroke engines. But because they have bigger built, they are also heavier, which can affect the boat’s acceleration.
On the other hand, the two-stroke outboards are generally less expensive (even with DFI technology) compared to four-stroke varieties. But they are also less fuel-efficient and less environment-friendly. Two-stroke outboards also require to be oiled regularly, adding extra running expense for you.
If fishing is your primary activity when boating, the outboard motor that you should choose will depend on your fishing style.
Four-stroke outboards are best for long hours of fishing that requires low to medium-speed cruising.
Meanwhile, two-stroke outboard motors are well-equipped for fishing off-shore or in bad weather conditions because they can provide instant acceleration to overcome large waves.
Update: 12-Month Extension for Carburettor Outboards
Last March 25, the Department of Environment and Energy (DEE) announced that it will give importers another year to get rid of their remaining stock of non-compliant carburettor-based outboards. The companies can either ship the outboards overseas or scrap them altogether. This extension was given by DEE after the drought affected the sales of outboard motors in the country.
Need A Loan For A New Boat?
The changes to laws about outboard motors aim to take the pollutant engines out of the Australian waters. Whether you are buying a two-stroke outboard with direct fuel injection technology or a four-stroke outboard motor, you can congratulate yourself for doing your part to help our environment.
