Factual videos like this Dan are beyond price, thank you for taking the time to share your hands-on experience with us. I'm absolutely definitely going to convert my Sloop this Autumn. One thing that I would dearly love to understand more is regeneration (hydroregeneration) how much energy can be recovered and at what speed.

Magnific!

[@davidraphael5074]

thank you. A very useful video that you have shared.

Dude, I'm converting a sailboat and you helped me a lot!. I have the old Atomic 30 motor out of my 30' Irwin and getting ready to buy components to convert. I have a 15 hp Tohatsu ob on the transom as well but want both to be more safe with the electric backup or main power system. Cheers!

Great job! I'm curious if the setup would work for a folding prop? On my ICE engine, I need to put my drive in reverse to stop the Prop from spinning while sailing.

[@artfulalias3984]

Interesting project. Thanks for sharing. Metal jewelry is very dangerous around DC with high current available, even at low voltages. Voltage that wouldn't even shock you will burn a finger off in a second.

[@denisemartin2542]

Nice job and thank you. I cant afford some of the new proper-flash setups

[@snakeplisken4278]

So what is the displacement of your boat? How long can you motor at 4 knots in calm conditions?

[@parris1871]

Hi, I did a very similar conversion on a ski boat. I too had major heat building in the controller. I ended up installing a heatsink and fans. I have very little throttle control and the engine cuts out if I push it too far forward. Are you have the same problem? My prop is a 3 blade 12x10. Guessing I need a smaller prop. What size prop are you running. Thanks, John

[@JohnBraman413]

what model coupler was that? they have a few different models on their site.

[@RulgertGhostalker]

i sized a system for a little Grinde 27, using one of the newer axial flux motors and got the pack down to 24V ( 25.6Vnom ).....that's the gold, because the system can still be electrically floating.. On Salt, anything over 25.6Vnom ( up to 51.2V Max nominal Li-Ion ), you really need the center tap sea ground, to center reference the pack; but as soon as you put in a sea ground, you need faraday cages, and a way to rote lightning current to sidarcs..

No problem with Direct-drive, no Gear Reduction?

[@rainfinger]

Informative video, we are an electric drive, presently cruising the Bahamas.

[@RulgertGhostalker]

there may be some provisions, in the emerging code, having to do with connections; which may allow for higher voltages than 51.2Vnom. but i think that center tap sea ground may have to be there, at some point; for packs over 25.6Vnom.......but as it sits at the moment, electrically floating packs are still limited to 25.6Vnom

[@user-gx9fs6lb4u]

What changes did you have to make to the software for the controller yo make it run? I’m have a terrible time setting it up.

[@Condor1410]

This is awesome i want to install the 48V 5Kw on my 24foot Boat do you have a Video on the Batteries?

[@goldenmotorNA]

Check the longer version in the description also you can use any kind of batteries . Email me at [e-mail]

[@ArcticSeaCamel]

Looking good! Thanks for the videos. I’ve got 3kw version in my 27 footer. Do you happen to have any energy consumption figures with different speeds? It would be very interesting to compare. The info I’ve got from different sources is that regardless the boat size, the good speed to go with (as energy consumption point) is around 3-3,5kn. But not faster. For that over that speed, consumption rises rapidly without any reasonable speed gain.

[@bobbrugus6917]

Check out kzbin.info/www/bejne/kKPVoX5sh8eZfqM for test data he’ has it up there with and wo sail up in zero wind

[@clivestainlesssteelwomble7665]

You might have to experiment with your prop size and pitch to optimize your performance.

[@drift8021]

Total cost?

[@todddunn945]

Instant torque doesn't matter on a sailboat because the prop limits the amount of torque you can transfer to the water. If you do the calculations for the prop the amount of torque the prop can handle is much less than that provided by a small diesel. The only time having lots of torque at low rpm matters is when you are turning a BIG prop like on a tug boat.

[@lasseloschenkohl3725]

That's interesting knowledge! I haven't thought about that either, and maybe I'm too focused on trying to make my upcoming electric conversion match my current 10kw/38nm diesel engine. Would there be a way to figure out what sizing of the new electric motor would be appropriate Thank you in advance Best regards

[@ashtongrist]

QUESTION #1 IS ALWAYS HOW MUCH IS THE FUCKING THING!

[@goldenmotorNA]

Check the links in the description. Pricing changes so there is no point putting it in the video

[@sillyoldbastard3280]

But why... my yacht uses bugger all diesel.

[@sharonbraselton4302]

too much engy go hybdride
