Rock the Boat: New Yamaha Harmo electric outboard motors!

[@mysticpointwatersports204]

very nice ... and encircling the propeller as i said before would be far more efficient than open propellers

[@YachtingInternationalRadio]

Thanks for tuning in guys!

[@imtheonevanhalen1557]

Not at all....this design for safety was looked at a LONG time ago, but the extra surface area of the shroud created so much drag that the idea was dropped completely.... Seems like a great idea, like a ducted fan, but water behaves much differently than air.....

[@myresponsesarelimited7895]

Depending on the hull, it can be for displacement hulls due to speed, but yeah as the guy above said - it does ad drag on an outboard driving a plaining hull because resistance is increased exponentially with increasing speed, you mainly see it on IRBs for safety reasons, otherwise you only see it on large displacement hulls

[@myresponsesarelimited7895]

@@imtheonevanhalen1557 I agree with what you said except the bit about aerodynamics and hydrodynamics being so different, i believe they're no more different than hydrolic and pneumatic rams, same thing- thicker medium, the first large foiling boats required programming to keep the boat flying in wether, even the Americas cup cat's are likened to flying a plane, not so much in the basic principle, but in terms of staying on foil as efficiently as possible, and it was aerodynamics that gave them a head start

You've done a great job saving us from anything Cannes or Monaco related 😊👌. Thanks again for the news.

[@Ca55-WP]

Haha thanks Idi! It was driving me nuts as well! Glad you enjoyed the episode :) In future I hope to be able to return to the longer format videos I was producing but for now, this is what I can provide and I'm just glad you're still watching it and enjoying it :)

[@idib1739]

@@Ca55-WP Don't worry too much about the length. It's short and sweet but still very much appreciated. Don't stop.👍

Excellent execution by the sherrifs

That sub! Would love to see inside.

I’ll wait for the nuclear powered outboard. Abundant horsepower and endless range.

good

Range? Remember to account for round trip distance, wind and tides or you got a long swim home. Not like you’re gonna top it up at a gas dock.

Why do you spoil your videos with music of some sort. You are hard enough to understand as it is. Get rid of the music, it’s not needed.

[@agentdoubleo7636]

Oh please. Don't watch

[@dopeytripod]

so amazing!!!

[@fredm529]

IS Stern drive, no outboard

[@georgedoolittle9015]

Absolutely.

[@Micington]

was hoping the harmo had more horse power hahah

[@YachtingInternationalRadio]

It is electric? Thanks for tuning in!

[@danmallery9142]

Yeah, that is pretty low. However, its not quite as bad as it sounds. Since an electric motor has peak torque almost instantly regardless of RPM, it will feel like about 3-4 times the HP rating in acceleration.

[@MrHatetheplayer]

ah yes, electric outboards, just another decade away...

[@dubes5594]

Trolling motor with artsy-fartsy plastic covers

[@TheCort1971]

an actual google search might be in order. or just make silly comments that have no basis in reality

[@MrHatetheplayer]

@@TheCort1971 show me an electric outboard that's the equivalent to the power and range of my 9.9 Merc for under $1500, have fun with that google search, I'll wait.

[@TheCort1971]

@@MrHatetheplayer under 1500? no. but the savings in fuel and maint. offset the 500 increase in price. the batteries are not cheap but they are getting cheaper by the month. i build my own stuff. over the course of a few years its much cheaper.

[@MrHatetheplayer]

@@TheCort1971 so you mean like, in a decade or so away?

[@tophat2002]

9 HP equivalent.. hmm.. need battery.. once u get battery you'll want a bigger one for auxiliary power.... Gets expensive to catch a little fish

[@jonwallace7015]

Reliant robin engine

[@bleezham]

harmo needs to be outboard tiller... Will corner the market as it meets electric only requirements AND salt. no more need for 2 motors. Not to mention trolling motors are awful

[@agyekumization]

Hope they come in solar

[@YachtingInternationalRadio]

Solar is making HUGE waves in the Yachting Industry, so sure it won't be long before the technology makes its way into the smaller crafts.

[@K.J.Ray421]

Yes, it doesn't make sense to not sell it as an outboard that can be mounted to any vessel. This would be perfect for sailboats with no other motor. It seems like it'd be much lighter than other electric outboard options.

[@bleezham]

@@K.J.Ray421 torqueedo comes to mind, hoping to compete and bring prices down...

[@bleezham]

@@K.J.Ray421 Depending if battery is external will effect weight. Check out torqueedo for your sailboat as an option available today> PRICEY but has been around for awhile and is popular for sailboats. Couple of other competitors something by name of NAVY 4 (googles it)

Yeah ill pass on that Yamaha Harmo. They better stick to gasoline outboards. There's no way in hell id trust that thing to take me fishing. Especially if its in the ocean or offshore.

[@donkanis6141]

Your great grandfather told everyone that automobile would never ....... ever .....replace horses. Elco has a 180 hp motor out now.

[@DIYDaveT]

@@donkanis6141 I have no doubt that they can make a 500 horsepower motor. But the battery technology does not exist to power this for more than a few minutes. Not even when we are talking about a large yacht such as I own, a 42' Chris Craft Commander which barely goes 16.5 kts burning 35 GPH on twin 454 Crusaders @ 600HP. Propulsion is a system. It is the weakest link that counts, not the strongest.

[@donkanis6141]

@@DIYDaveTYour a bit behind in your info. I have a 41 Hatteras with twin Detroit 671’s. I'm also a Tesla shareholder and keep very current with Tesla tech. Replacing these heavy engines and loaded fuel tanks with a 4680 battery and twin 500 hp Tesla ELECTRIC motors (which are MUCH more powerful than diesel) would be a big big improvement in every way.

[@DIYDaveT]

@@donkanis6141 LOL. It seems you are a bit behind in your physics. It takes the consumption of 35GPH of gasoline to move my yacht at 16.5 kts. This is about normal for this older, solid glass semi displacement hull using gas. Diesel is a bit better. 1 gallon of gas is about equivalent to 33.7 kWh of electricity. My boat holds 300 gallons and only gives me 150 miles of range at cruise. Miles of range are what boaters care about. Having electric motors does not change the amount of energy needed to move it from point a to point b at a given rate. The efficiency of conversion of fuel to kinetic energy (motion) for gas is around 35% (there is a range but this is ballpark). The efficiency of conversion of fuel to kinetic energy (motion) for an electric motor is much higher, realistically 90% or even a bit more. So let's just call it 3x more efficient for round numbers which is being quite generous to electric. That means it needs 1/3 of the kWh stored in my gas tanks in order to do the same work (traveling 150 miles at cruise speed). My gas tanks store 10,110 kWh electrical equivalent worth of fuel and so in order to get the same result from electric you need about 3300kWh of electricity. With the new cells, the Tesla model 3 has 82kWh in its battery pack. So you would need a whopping 40 of those packs at untold cost in order to match what I can do with 1990 gas engines. Unless and until battery technology makes a major leap they remain a hobbyist technology for boaters.
