300 HP Electric Outboard.

I like the comments, especially the one about trailing a propeller to charge the battery.
Anyhow, we're saving the planet, apparently.

And the two batteries only weigh 380kg each - 760kg all up, need specialized equipment to replace them. And I've asked about the process of recycling lithium batteries and still don't have a good answer, so far cost is too great and I suspect a lot being dumped, our local Battery World shop won't take them anymore as they had so many out back of the store they didn't know what to do with them. We are definitely saving the planet.

I think that the next "big thing" is going to be in battery size and charge time, I just kind of think the minute that breakthrough occurs, electric cars will take off big time, boats, maybe not for the rec user, but, ferries and stuff, yep. When you can charge your electric car (from renewable) in a few minutes, then the world will change almost over night.

These electric motors are very expencive some car electric motors are nearly as dear as a diesel motor so a boat one would be twice that price.

I could almost fish now with a electric setup
130pound transom mount plus the standard bow mount and 6 200ah lithiums for about 120kg
10k is still cheaper then a new 50 four stroke

yes it would be slow and for estuary’s and freshwater stuff but if fuel was stopped it would still get me to the same spots now
would just have to launch close to spots etc

evs Charge quick enough now the issue isn’t charging times its the manufacturers can’t get enough into the country
For everyday use cahrging is a non event and for bigger trips like I’m doing it’s 20mins at Goulburn there and back

I’ve done 33,000kms is far in the Tesla and charging has been a non issue

Electric boats that compare favourably with ICE will not be a thing in my lifetime.

You won't have to wait that long, "Extinction Rebellion" predicts the world coming to a complete end by then.

Or we will wobble ourselves silly, have a read of this article, it will set your head spinning.

But that's getting offtrack of this post.

Yes, I can see that, but, as it stands, plugging into your power point at home is not going "Green" and it doesn't take a few minutes, plus the battery is hideously heavy and expensive, once that is over come, and I feel confident it will, then the game will change real fast. The current range of electric vehicles are more than adequate for the average user, most just "don't like them" for no good reason, it's just "because" most big companies have solar panels to run charging stations in supermarkets and car parks, but they are only good during daylight hours! Times are changing, and we will slowly accept the change, but it won't be next week......
edit.....unless houses have some kind of wind/solar charging, our ancient power supply grid could not cope with a Tesla in every house being charged.

I think that's a wait and see thing, until "they" find a way to make Hydrogen cheap/free, and overcome potential storage problems, then so far, it's just a "maybe"

"edit.....unless houses have some kind of wind/solar charging, our ancient power supply grid could not cope with a Tesla in every house being charged."

If you talk to people in the electrical side of things most appartments more than a couple of years old can't handle the loads, mate in Port Stephens had the issue where the BC manager wanted one installed fir use by him but the load was such that was the only one that could be installed so yhe rest of the unit owners wouldn't be able to have one. That idea got squashed, and it by no means is an isolated case.

[Noelm]

Yep, it's another "hurdle" that no one wants to talk about! It's why some kind of renewable/free source needs to be installed in houses. I think the trend will be solar with big storage batteries (not much of an issue in a house) to run at night or when there's periods of cloudy days. So far it's all hopes and dreams, but I think the answer is closer than we think.

I think the price issue will certainly be solved. The new Sodium chemistries may already be there, it’s just a matter of time to get the, into mass production to see where the pricing lands. It will certainly be cheaper than current lithium chemistries. The charging rate I see as the next hurdle. If you can get another say 300km from a 30 minute charge then I see them becoming a lot more mainstream. Even now, with the albanese gov’ts reduction in taxes on EV’s the cost have come down a fair bit. If Sodium batteries can bring them close to their ICE equivalents, it makes total sense for people in large cities to convert to EV’s for their commute vehicles.

the problem there is infrastructure. In a lot of cities, there’s lots of places like in Sydney where people have to park on the street. Local governments hate people running caravan leads from their homes across footpaths to charge their cars. Imagine if everyone wanted to go EV, the infrastructure costs would be enormous.

There are a lot of governments around the world that are trying to force everyone EV, well before the technology is ready. The big problem there on top of infrastructure is energy density of the chemistries. Chinese battery company CATL say their next gen Sodium battery could get as much as 200wh/kg from a sodium battery. If that chemistry has no lithium in it, it could be a game changer for bringing down the cost because it’s equivalent to the best lithium batteries (or close to it). But that’s still no where even close to being able to replace other forms of transport including dual cab utes. Dual cabs and the landcruiser take up 5/10 of the top selling vehicles, including the top 2 (Hilux and Ranger with triton in 4th). An electric equivalent could not replace those with current energy densities.

Imagine towing even a 2T boat from Brisbane. You’d be lucky to get to the Sunshine Coast to go fishing. Forget about an annual fishing trip to 1770. It would take you 3 days to get there and 3 days to get home. Forget about boats. Only the biggest virtue signalling gristle tuggers will buy these in the next 20 years at a minimum.
