I'm presently using a 2kw generator (Harbor Freight) and a 48vdc golf cart charger. Also have 200 watts of solar power (12vdc in series for 24vdc with a boost controller to 48vdc). All of that is

Is this a commercially available unit or something you put together? That is a reasonable power output for continuous cruise on about a 10,000 lb monohull I think.

I have a 4.5Kw,?48 volt,?alternator powered by a 8hp propane fueled engine. But no boat yet. Sigh?

I believe the current (amp draw) that you see from the sevcon is motor amps not battery amps Brian D. HAll

Darn auto correct. I meant sails....Sent from my Bell Samsung device over Canada's largest network.

Not a Duffy but I'm putting together a little tremolino trimaran no sales just electric. Epropulsion nav three.NickSent from my Bell Samsung device over Canada's largest network.

Has anyone put solar panels on a Duffy electric boat? ?48 Volt. 16 batteries. I have the boat. I have a Morningstar controller. Thanks for any insight ,ideas or warnings.

Sure, if the voltages reported were the same a 20% higher current on the Sevcon would be odd. Definitely check this because when you went to a steeper pitch the motor current went up for a given

Agreed but Sevcon was reading about 20% higher than Victron. And I think Sevcon and Victron voltages did match but I will have to check that. There are some calibration factors in the canbus

Regarding the discrepancy in current readings between the Sevcon and Victron, it could be due to the Sevcon reporting motor current while the Victron reports battery current. The controller, being a

Have you got any performance data? My setup is very similar. 12500lb, 33ft (28.3 LWL) monohull. I also have the Thunderstruck 12kW liquid cooled (ME1616). I have 3:1 reduction that I fabricated

You can also get SB50 / PP75 contacts that support 6AWG, 8AWG, or 10AWG without a bushing: https://powerwerx.com/anderson-pp75-sb50-loose-piece-contact

There are sleeve bushings for those Anderson connectors, to better allow the use of smaller wire: https://powerwerx.com/anderson-powerpole-reducing-bushings I have the Hangkai 2.2kW motor, and used

John, I have the Hang Kai 1.2 kw as well. It's going on a 12 foot cat dinghy I'm building. The motor is direct drive, no gear down at all. That's why the prop is so small. I consulted with my

I have a 34’, 13500 lb keel/centerboard cat/ketch with a Thunderstruck 12kw watercooled kit. Prop is 17” x 13” fixed 2 blade. I am using the “large” Thunderstruck 2.5-1 gear reduction which

Hi folks I mostly lurk and learn. I think I may have asked this some time ago but wondering if there have been any developments.? Is anyone 3d printing props with any success? I have a nav 3 which is

Hi John, I use 50 amp andersons on my dinghy motor. They do take a beating. I have to clean them every few months. Keep in mind, I get them wet frequently and they have taken more than a few dips in

John, As far as I’ve spirmented, you are thinking streight and are barking up a sound tree. With a 36V Motorguide and a ebike battery, I push my HA-18 at about 4 mph. Your prop is as important

I'm planning to use an electric outboard on the West Marine RIB 310 for my trawler.? The dinghy is about 10' long, weighs a little over 100 pounds empty, plus 2-3 "solid sized" adults, plus motor

Thanks Chris, I did briefly think about it. We've a 48V multiplus ii, the 5kva version, so not enough by itself. Another A$8,500 for the 15kva version, and still have to buy a large enough AC
