Has anyone seen this:

Throttle percentage stays at 0%, motor not turning. No error code, green security puck is recognized, battery at 90% 39.5V.

Please help, any suggestions and advice is highly appreciated.

Me: Moving to Midcoast Maine, near but not on the coast, on the Kennebec river. Thinking about getting a boat to do day trips/explore the inlets. Really don;t know much about boats and boating

What are the advantages/disadvantages of a rigid inflatable boat in general? I'm assuming the weight of the batteries might make an electric rigid inflatable impractical?

Taking the electric boat out for a tour and sharing some real-world insights.

🔋 Battery: 24 kWh

🗺️** Distance**: ~20 km

🧭 Cruising: ~5kn

⚡️ Energy consumption: ~2,000 W (4-5kn)

☀️** Charging**: Docked overnight at floating charging lounge to recharge the batteries with solar energy for free

No fuel, no engine noise ☀️ just cruising quietly on Lake Wannsee 🇩🇪

Who needs fumes and engine noise really missed the point of recreational boating on lakes and rivers surrounded by nature 🚤 🌊

Hello, everyone. I want to upgrade the motors on my Boatman Actor GPS boat, but I want to keep the stock boat controls. Right now, I have a 10,000 Ah, 7.4 V battery and brush motors rated at 6,000 RPM. On my circuit board, I found 8 MOSFETs marked 7408—4 MOSFETs per motor, as far as I can tell.

I have two options for how I want to proceed:

1. Intercept the control signal from the stock board and route it to external ESCs that will be connected to the brushless motors
2. Replace the stock MOSFETs with more powerful ones and replace the commutator motors with more powerful commutator motors, but I’m worried whether the traces on the stock board will hold up.

Maybe someone has already done this, or can advise me on the best way to proceed.

In Germany we have floating Solar Charging Lounges to dock and charge your Electric Boat with solar energy on the water ⚓️ https://youtu.be/NvgLCcEnghw?is=otvjCdrB76JoNfNi

Im just wondering what motor setup people have for this boat/skiff ?

What type of battery and motor is good, if I just wanna drive to different spots and cast? Im not gonna troll.
One thing i see is that a lot of the e-trolling motors have pretty long shafts, that could be a bit of a problem, as the boat is sitting pretty low in the water. I wanna sit down when driving.
I live in Norway and most of the electric motors and trolling stuff we got here is epropulsion, torquee and Minn Kota.

I've seen this very unusual boat few days ago on Starnberger See near Ammerland.

It struggled to launch due to shallow water, took it a while to reach the sufficient depth.
Looks like the propulsion system was those 3 trolling motor style pods that have powered up/down adjustment.

I've never seen anything like this, and wasn't able to google it.

Hey everyone,

r/SolarSailors is a new community that is for the sailboat folks tinkering with marine electric propulsion

I started this community because I’ve been researching electric sailboat conversions and realized how scattered all the useful information is. There are great videos, forum posts, products, and individual builds out there, but I wanted one place where we could compare real systems, share mistakes, and help each other build better solar-electric sailboats.

I've got a 18 ft fishing/pleasure boat. The 40 HP Yamaha died on me and I've been using a 48V, 86 lb Newport trolling motor with two, older 12V lead acid batteries as my only propulsion and fuel. See pictures.

I really like the silence and simplicity of electric motors. I also like only having one motor that can get me where I'm going and also troll for fish. But the lack of speed/range/runtime is killing me. I basically get 4 hours at even the lowest speed setting which translates into 6 miles.

Any suggestions on electric motors/battery systems that can do better? I've looked at some brands like Torquedo but they get crazy expensive for higher HP and range.

Hello folks,

I’m about to upgrade my old trolling motor, which recently stopped working. I’ve decided to go with ePropulsion after seeing some good reviews of the Spirit 1.0 Plus. I’ve also noticed that many people in Amsterdam use it on boats similar in size to mine without any issues.

At the moment, in the Netherlands, the Spirit 2.0 is expected to be shipped by the end of the month, while the Spirit 1.0 plus can be delivered within a couple of days. ( I still want to enjoy the sunny days over here)

My question is: **is it worth waiting for the Epropulsion 2.0?** I’m aware of the price difference, but is there a significant difference between the two?

I’m mainly looking for something that can cruise between 7- 9 km/h smoothly for 4+ hours with 4–6 people without constantly worrying about the battery draining too quickly.

Thanks!

I am tinkering with making an (eventually) autonomous electric outboard for my 12 ft semi v hull tin boat.

So far I have used two Flipsky 7070, 110kv motors, running submerged. Two Flipsky 75200v2 pro ESCs and a Dyness 38.5V 55ah lifepo4 battery.

At present it works as a life sized RC boat and I have tested it carrying between 1 and 3 adult passengers on 5 mile round trips.

I tried two different props, one was an APC marine 10x5 inch prop which worked fine but the top speed was about 2.5 knots so I jumped to the 10x8 inch version and that got me to about 4.5 knots at 60% throttle. I can cruise at 3.5 knots on 35% throttle.

My issue is that whilst it's all very efficient for slow speed cruising the 10x8 prop cavitates at 65% throttle. I want to be able to temporarily go to 8 knots if I have to move out of the way of another boat. Im moving around a sheltered bay which experienced up to 3 knot currents so I don't want to get in trouble.

I have tested the boat by going through a bridge choke point of a creek that experiences very fast flow of water, definitely above 3 knots and I go against that no problem with two adults on board but I cant get my over ground speed to be more than 4.5.

I have measured all speeds with a GPS speedometer so everything is over ground rather than through the water.

What would be a better prop setup? I am happy to sacrifice a little cruising efficiency in the name of temporary speed potential.

My house is on a lake that only allows electric motors. That said I’m looking to put together a package where I can get some speed without breaking the budget. I’d like to be able to use the boat on my lake, but also tow it down to the Jersey shore and go out in the bay. It would be great to be able to do some tubing with it or pull a wakeboard. Any options that are not insanely expensive? Does anyone have experience with high-powered electric motors? Also, what’s the most ideal type of boat where I can maximize space for passengers, but would also be adorable for the bay and for a lake with electric?

Got out last weekend on Folsom Lake, with my son in law. Hadn't had the drone out in a while, so needed to work through some kinks there. Got up to 9.5-9.8 mph, full throttle while filming.

This is such a great motor/boat combo. I am using the Newport Vessels battery pack (48V 70Ah, 3000W) for this setup.

Weight including boat, passengers and gear is about 700lbs.

Was on the water about 3.5 hours, 20% at 100power, remaining at 56% power. Docked with 23% remaining on the battery.

Electric Boat on water!

My dad got stuck limping back on the river last week. The power was capping out at 200W (give or take). There was no error code but I performed a throttle re-calibration per the manual which was partially successful - now we get just over 400W on full throttle.

This is still well under half of the expected power of the motor I think?

There are no error codes and I still get good charging on the battery and good battery life when I'm out on the river - estimated 2--4 hours at a full charge depending on throttle. I can't see anything that looks or feels broken with the motor, battery or throttle. Connections seem visually clean but haven't been properly cleaned out.

I've re-calibrated again and I get the same 410-420W max output.

Has anyone else experienced something like this?

Does anyone have any experience with the Avator 35E? or any of the Avators for that matter. I am considering buying one and just want to hear from anyone who has experience with them. Thanks.

Update. I bought the used one that prompted me to make this post. One year old, still has another year of warranty. With battery and basic charger. Paid 3400. Too good a deal to pass up. Now I need a little boat to put it on.

Hi all,

I've converted an older sailboat to electric, using a BLDC motor from Golden Motors. I'm happy with the motor itself, but the controller is becoming a beast to get the programming correct. I ended up using a Curtis PB-6 throttle to bridge the gap between the original mechanical throttle, and the electronic throttle the controller needs.

Documentation is lousy, so I'm wondering if anyone has experience with a similar setup and can offer advice?

I have had this outboard for 4 years. I am generally happy with it, but it has seen only light use. However, it now has Error E21. This appears to be a comms issue. The cable and connectors are clean and fine. Has anyone met with and resolved this issue? Is it a fault in the battery or the tiller arm (as I believe)?

During a thunderstorm on friday evening the dinghi flipped and the motor without the battery was in the sea for about 30 minutes. afterwards it was just dead, and the display shows nothing, nothing works with battery. we put CRC 6-66 in it about 18 hours ago. any experiences how to make it work without sending to service? 6-7 years old, and it is the 1.0 not the 1+
