Finalist in both Commercial Marine Design and Marketing Awards

We are proud to have been judged as finalists in two categories in these awards.

The 2022 Commercial Marine Project/Design or Manufacturer of the Year award identifies product manufacture, design, and shipbuilding within the Commercial Category in the Australian commercial marine sector.

The 2022 Marketing Strategy of the Year award acknowledges the success of an innovative and effective marketing strategy implemented between January 1 – and December 31, 2022

As Australia's only outboard manufacturer and only electric outboard manufacturer, we are working at the cutting edge of the marine industry in electric outboards, electric boats, and electric jet skis.

Electric Boat Propulsive Power Explained.

Why kW to hp conversion formulas aren't that helpful in electric boats

One of the first questions people ask us is what horsepower does a kW engine equate to?

And often they have heard of the international hp to kW conversion formula. Which is 1kW = 1.34102209 hp

This is fine, in theory.

However, in practice, we find that calculation is not at all useful.

Why?

Because it doesn't take into account the instant torque. And the advantages of electric in the low to mid-range RPMs. The RPMs you actually need to get on the plane or get going - or dock for that matter.

So that's why we refer to propulsive power at the propeller as the important power equation. And why we comfortably say that whatever propellor the ëlectric outboard can drive, that's the hp equivalent.

So let us explain how this works.

In a combustion engine, the engine has to develop enough RPM (revs per minute) to reach idle speed. This usually occurs at around 1000 RPM, and you are in idle until that point.

Now you can get into gear and start to develop the advertised hp. But the fully advertised hp doesn't occur until the engine has reached around 5/6000 RPMs. So if you are at mid-range, you have not got all the hp of the engine available to you. An example would be a 40 hp outboard, which would only have around 25hp or less available at the low to mid-range of its RPMs.

Now electric outboards behave very differently. They have full power (instant torque) available from the first turn of the propeller. And a flat torque curve.

This power is important in planing boats, as you want to efficiently get out of the displacement hole and on the plane. Then you can reduce power (and amp draw).

In displacement boats, this instant torque gives you high torque at the low range RPMs - perfect for creating that momentum you need to get the boat traveling. The ideal for displacement boat efficiency is to use the biggest propeller you can, turning at the slowest rate.

So back to propulsive power.

When you are looking at electric outboards, we will ask you what propeller your current outboard turns (pitch and diameter). From there we can work out which is the right kW outboard for your boat. By the way all our outboards are made in Australia.

New report says the industry will be worth $USD 20 Billion

That's the prediction of a report from IDTechEx estimates that “the market for hybrid and pure electric boats and ships will rise rapidly to over $20 billion worldwide in 2027“. 

While EClass Marine has been one of the first manufacturers, and still the only electric outboard manufacturer in Australia, the report says there are now more than 100 marine electric manufacturers worldwide.

These companies are working on everything from electric ferries and new hybrid container ships, to the small kW trolling motors now loved by fisherfolk.

The first electric ferry in the Southern Hemisphere (NZ) had its maiden voyage just last week.

And Outboard giants Mercury and Yamaha have unveiled their first fully electric concepts. Although these seem to be lower kW offerings and not available to the market as yet, it is a sign of the industry direction.

At EClass Marine we think that once the marketing might of the large manufacturers gets behind electric boats, a lot of the skepticism will wash away.

Having said that, there is a lot of work to do for the mainstream adoption of electric outboard motors. Buyers have battery range anxiety (interesting as it is no different from having a fuel gauge and planning your trip), are not used to paying upfront for batteries.

Also, not many manufacturers are producing the 20kW (40hp) and higher electric outboards so common on many craft. EClass has put a lot of work into this segment with our 20kW Ultra electric outboard engine

The report also indicated that access to parts may be a barrier to electric outboard motor adoption. That's why at EClass we are using tried and proven 2 stroke outboard casings. Any corresponding Yamaha part and accessory will fit. No waiting for a proprietary part to be shipped, and a competent marine technician should be able to install it. We have a 3-year warranty on our electric outboard engines for private use.

Revolutionary new charging Bouy for electric boats and electric outboards

For all of you who mock electric boats and say how do you charge out at the reef!

Maersk Shipping has partnered with the world leader in offshore wind generation on a buoy system that will charge the electric outboard batteries and hybrid vessels using electricity from the wind turbines. The first use will be for wind farm service vessels but the long term goal is to use them for boats and ships of all sizes and have a significant impact on the use of diesel fuel.

Eclass Outboards have long believed that solar charging will set electric outboard motors and electric boats apart. We have a portable solar power station Ecoflow DELTA Max that does this job and can be kept on board.
