If you'd like a little more or a little less power, push that number up or down a bit.? You now have an estimate for the power of the electric motor you'll need.? Others have commented on how some

It's a YSM8 so 8hp or 4.9kw at 3200 rpm

What is the HP spec on the Yanmar engine you wish to replace? -Halden

Darin: Those are some great points. I agree with you, after doing some more research, that these motors are probably not suited for sustained 3kw output. They cheap out by providing a controller that

These are all very good points! Thanks for sharing !! My system based on the go cart kit works for me because as a day sailerl I truly just use it to go in and out of the slip for the last couple of

My 2 cents: 1. Smaller motors are more likely to overheat. Larger motors have more mass and convert more of the energy to torque. You can offset this limitation a little by using higher voltage.

Watch that I read 72 vdc. The kw looks a little low. Let us know. Good luck On Sun, May 9, 2021 at 11:51 PM, Ashley Holliday via groups.io<rasholly51@...> wrote: That motor and

Dam 12 yrs ago I lived in Manasquan . Now in SC.I have an albin Vega looking to go electric.

Thanks for the details. I have a feathering prop (J Prop) and to get it to feather with the diesel I would shut the motor down in forward, shift to reverse, then back to neutral. It would then stay

Hi Dan, My old motor was a Saietta. Basically identical to the Thoosa. New motor is a Motenergy ME1803.? I don't recall the specs but the Saietta has a thrust bearing that can handle many many times

Do you need to lock the prop shaft to get the Autoprop to feather for sailing? If so how do you plan to do that? What motor is that? Looks like a Thoosa? Is there a thrust bearing in the

Well I have a 23 ft power tri, using bits of a sailing tri I built 40 years ago and found in a NC field. 2 years ago. I found a deal on a complete Elco 20HPoutboard with all parts and 4 12

Just an odd observation; on the sale link page if you click the specs tab they are listed as 45 W 15.4 V which of course doesn’t make sense for their size. On their website it has the right

Hi Ken, Yes, and according to the manufacturer it should perform better than a fixed prop. I was getting about 22 watts at 3.8 knots. Haven't had any real wind for testing yet. Hopefully this week.

There have been links to Lifepo4 batteries on this list that are effectively cheaper than lead acid when you consider you only need half the capacity. Also bigbattery.com just had some 36v packs that

Hi Matt Very interesting. I’m a broker and I have sold several boat with Diesel engines and Autoprops and am well aware of their advantage. I was unsure how they would translate to electric drive.

Hi Ken, ?I use my own boat for testing. I'll try and write it all up one day with specs and measurements, but briefly.? I started out at one extreme with a tiny 12' low pitch prop. This gave me a

Alright! I would need to double that then at least. But I'd have to plan so that I can start out with a smaller set of batteries in paralell 48v and be able to scale up from there. Thanks for the

Very interested in your autoprop and why you chose it. Tell us more about it please. wrote:

Yes it would if the boat weighed about the same as the mobility scooter. Otherwise you're gonna need a wee bit more. 20AH lead acid (which means 10AH of usable capacity) will run your motor at 1000
