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.

Wife and I are moving to a town in Maine, near the coast, on the Kennebec river. I think I'd like to get a modest sized, trailerable power boat, to make day trips. Not interested in sail.

Full disclosure, I'm not experienced with boats, though my cousin lives in the same town and is a licensed "100 ton master." Happy to take my time and learn. My goal is not really high speed, just exploring the inlets and by-ways.

My wife is not enthusiastic. She dislikes the fumes and noise and vibration of a power boat. So I'm wondering about electric boats. Like finding a 20 ft boat with no motor or a derelict motor and converting it to an electric boat. This is obviously not something to be undertaken lightly, but maybe there are some sources that experienced boaters might know about?

Thank you for any suggestions and for not mocking someone just exploring the idea

We’re taking a look at the future of water sports and Test Driveto the world’s first production electric performance PWC.

The big questions: How does electric power compare to a 300 HP @SeaDoo?

And how do you deal with range when there’s no fuel station or charging infrastructure around?

For the test, we’re bringing our SolarYacht into the setup and turning it into a floating charging station. ☀️🔋

We’ll dock the Electric Jetski alongside the yacht and recharge it using solar power.

We’ll also talk about charging times, real-world range, and what it’s like to be completely self-sufficient on the water.

And then comes the fun part. 😎

With up to 120 kW (~160 HP), the Orca goes head-to-head with a 300 HP gasoline-powered Sea-Doo.
Acceleration. Handling. Top speed. And most importantly: Which one is actually more fun?

Electric vs. gasoline. 160 HP vs. 300 HP. Solar charging vs. fuel. Let’s see what happens. 🌊⚡

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.

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!
