Electric Outboards

Well it looks like the motor technology is there now....





I guess its just a waiting game for a battery or fuel cell that can give you more than a few minutes at WOT or a few miles at cruise..

I think these guys are worth keeping an eye on...

Batteries are big problem..

...and a network of (very) fast charging points to fill them back up again.....

Think - you pull in to a marina, & takes, what? 10 mins to full up & pay through the nose? That's going to be some peak power to manage that - at the same sort of distribution of locations as you can currently do with petrol / diesel.

Then of course you are lugging all this extra weight around, so burning more juice to propel it, and of coure all the electricity would be generated by windmills, and of course there would be no emmissions mining / transporting the ore to make the battery or tons of toxic dead battery when it's finished......



Thre idea seems good, but the overall picture might not be so appealing.

I spent a few hours last night reading up on the latest ideas in battery technology... One that might work is that you pull into a "filling" station and you can fill up with ready charged electrolyte. effectively emptying all the flat stuff and refilling at the same time. This seemed feasible.

I agree that currently its a non starter to look at electric for anything other than trolling however give it a few years and I reckon we will all be looking for cheaper ways to power our boats if fuel prices keep rising.

One thing these guys of E-Fusion do understand, is that an electrical outboard should not look as a square block plastic. Most of the manufactures make beautiful technical solutions, but don't think about looks at all.. What is this actually? Is it based on as Suzuki?

I think they use several engines as a base one of those videos is an E-tec conversion.

As long as it's efficient and effective and convenient, sure

Don't hold your breath though

My sons (well mine, he's five) RC car has a motor 52x30 mm in size that is between 1 and 2kw.... It would take your finger off in a second..... Very powerful, but the battery lasts for 7 - 10 minutes max (lipo)....... Batteries have a real long way to go yet, to get on the same planet as petrol.... Motors are there easily...

See IOM 'TT zero' speeds (102mph lap on 20% average bike max power)
