Very nice Video!! Thank you!

How do you change the batteries?

Would it be possible to install the electric motor on the shaft with a diesel engine still there?

Pretty cool video. I also wanted to do an electric swap but after seeing this bullshit price figure I’ll just pollute the planet for now. Just shows you how they control the market

Great information for my project. I would like to choose between mi diessel engine and an electric having both installed. Thank you very much!

Its interesting that my ebike hobby came from learning how to work on these things. A 1kw motor carries me at 30mph around town more often than cars do now

My god, just great, we live in Lantzville , I have been to your marina many times , also to pick up fresh crab mmmm. How's the setup today , still going good.

Love to have 100 solar boat .

Hello very nice video. How much ($)was the total material used? Thank you

Hi, i'm looking for information about how can i regenerate energy with the motor when i'm sailing, i kind of a recovery energy break system, anyone has some information about regenerative breaks?

Where did you install the batteries?

It would be more efficient to go direct drive without a belt, and if you needed to change the "gear ratio" resize/repitch your prop

Good on you, for increased performance try swapping the pulleys, increasing the propeller rpm, the motor can handle it, it's up to you with the throttle as to what the motor can handle

Hi OpenROV #272 - Quick message to thank you for your informative video as it helped me in starting my own build. I am designing/building a similar setup as yours but instead using two brush-less/water-cooled 48V 10Kw Golden Motors in parallel (driving one propeller shaft). If you are interested in following the build then I have posted my first video showing the motor housing:) Thanks again and keep the boat adventures coming!!:)

All hail the lords of corrupt inflation. Thank you for the honor of allowing my dreams to be crushed. ...good info!

I was thinking of downgrading to a battery motor but then I looked at it and decided "hell no", I am not an idiot. The silliest downgrade you can do is get a battery powered motor that goes about 15 miles before dying vs my diesel that goes 1,000 miles, costs less, refills instantly, and is super reliable. There is no real decision to be made guys. Don't fall for stupid politics - batteries are dirty and full of chemicals, expensive, pollute the world for 100,000 years after you dump the junk, and cost more. Nough said. Only fools get them.

I'm a bit puzzled. Your spreadsheet says that you have two batteries of 48V at 200Ah each which gives you 9,6kWh each or 19.2kWh total. In your video you said that you only had a 10kWh battery bank. I'm not familiar with those batteries and they are not available here but the LiFePO4 batteries we get here are not 48VDC but 53 to 56VDC which changes the calculation somewhat giving 53VDC x 200Ah = 10.6kWh or 56VDC x 200Ah = 11.2kWh per battery. I am assuming that the batteries are the rated voltages I mentioned and not 24VDC base meaning you had them in series to get the "48VDC" you mentioned. It is quite a nice detailed build video, well explained.

You are so concise. I love it

Thanks for your reply and great information awesome video

Could you please give me the approximate weight difference going from diesel to electric including fuel

I'm trying to buy an Elco electric inboard for my Catalina 27 but I'm running into phone apps. I don't even know if they make a control pannel for their engine. I would think an engine would come with standard gages that tell you RPMs, amps etc. Why on earth would I want to have to drag out a phone to look at this stuff? Not to mention the privacy concerns. This is just amazing to see a company pull something like this. Anyone know of an inboard motor company with actual equipment and no phone apps?

Nice job man ! Next step, tesla swap ?

Better ,go on diesel,nearly same cost uh 😳

I like my air cooled Chinese 168 F diesel. It's much cheaper and lighter than electric and it charges a battery well. The dry heat is welcome.

I like my air cooled Chinese 168 F diesel. It's much lighter and cheaper than electric and it charges batteries on very little diesel. Hot dry air is welcome in almost any humid weather.

Nice job, thank, but one must wonder, given the very reasonable price of used boats, whether it would be more effective to find another boat in good shape and upgrade. I’m thinking that if I were to replace the engine, an outboard or Torquedo would be my preference and so avoid the issues associated with the prop, shaft, bearing, etc.

this is a very useful video, but its really quiet, im at 100% at windows and 150% in sound booster in browser and its still barely hearable

Well done video - Thank you!

hey, very nice job. it's interesting to know the global budget about this conversion (motor, controller, charger, battery pack) i'm from belgium, and found a representative contact of Thunderstruck in Netherlands.. my boat: a Kelt Sailoat, 30 feet, actually powered by a Yanmar 2GM :) or the same project, this last summer, at LaRochelle BoatShow, a firm in France propose me 15.000€ (motor, controller, charger, batteryPack),.. interesting to compare enjoy the Sea ;)

This is an excellent video. Like you I also looked everywhere for something like this, and wasn’t able to find one. Thanks for making it.

why didnt you add more battery capacity to the boat? cant you add abt 50kwh?

I shared in my group

still no sailing videos? still got i?

Thought you did a very good job.

I plan on doing the exact same thing as you in the next few years.

Ne subscriber sending greetings from Tucson, Arizona. I contacted ELCO last year looking for information to complete an electric conversation installation. They were NO help and offered NO information.

Do you know how many KV your electric motor has?

I used their 5K kit. Very satisfied with quality and customer service.

I typed up a summary. Comments welcome. docs.google.com/document/d/1UWNwufQltgJFzrVRYG5jhMvtZHi4vHT0cVoOnr0EFM8/edit?usp=sharing

My worry is about how long it will last. I'd be happier with a water-cooled one

I recently installed an electric yacht 20kw in a 37' Irwin, and it was weak. The tides were stiff, and the run from dock to sail area was long. Electric is still a fantasy. Battery densities and motor efficiencies are a ways from max, and alternate power sources should be included. It was quiet and pleasant.

BULL SH*T STAY WITH A PROVEN METHODS I C E

Well done! I feel there was a point in the video where you reached no return - the electric engine *must* work :)

So glad you mentioned the waterproof eg4's I had not considered those for my build. They're now 200 more each than the server rack versions I was planning, and I'm buying 8, but the waterproof feature makes me think these are the better option.

Real men use diesel.

From your states it does not sound like it would be good for Island hoping and crossing the ocean. more of a lake option

We need more of these videos showing real life stories of electric powered boat coversions. A growth market for sure. Kudos!!!

Great video amigo!

I believe installing a E motor in a sailboat is a BIG MISTAKE.
