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.

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.

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

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

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

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.

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 as it sits at the moment, electrically floating packs are still limited to 25.6Vnom

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

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 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..

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

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

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

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