Thanks so much for taking the time to make your video. Some watchers will wish that you got your pros and cons discussed more efficiently, but I liked the slow pace of your discussion with the digressions, beach scenes and fish sandwiches. And I found most of your cons to apply to most all electric outboards and not to the ePropulsion specifically, which helps me keep it on my short list of motors as I do my research.

Nice video, worthy watch. We only use our dinghy to get to shore from anchorage we decided to get one of these as they are much easier to handle single handedly to transfer from our yacht to the dinghy. Much easier to handle two parts each about 10kg. No fuel spillage and smell, instant start, delightfully quiet, and much easier to control fwd and rev. I tend to run it at 400W max which is the sweet spot for our dinghy. It's each to their own on how they use their dinghy but for simple back and forth to shore I wouldn't go back to petrol.

Nice 👍 what do you do about leaving the dinghy unattended? I still have not found a good solution.

Great video. More people need to see it. These are great motors depending on how you use your dinghy. We talked before replacing our dead Honda 2hp with Spirit OnePlus and realized that our only use is to push our tiny dinghy to and from shore at anchorages. Dinghy is too small to row comfortably with two or more and no room for a bigger one. This motor is perfect , eliminating gasoline onboard, starting issues, maintenance bad gas issues, etc. However, our friends with the same sailboat use their dinghy to venture miles beyond the anchorage and at high speed. This motor would not work for them. Also we liked the way you broke the review up into segments and introduced each one. Thanks again. Good info here for many more than have seen it so far.

Thank you for your detailed and informative video. I will point out, however, that your comments between 8:00 and 11:30 min. regarding the diminishing returns of increasing throttle applies to other power sources, not just electric. If you had a petrol-powered outboard, as you increased speed, you would burn a disproportionate amount of fuel. P.S. I saw in the news today that the ENTIRE COUNTRY of Portugal was able to operate for 6 days in late October / early November relying solely on renewables: hydro, solar and wind. That's quite an accomplishment and worthy of praise. Parabéns!

Hi. The difference is that with more power eventually you get into plane and then you use much less energy. In a few year i hope we will have batteries capable of supply the required power for plaining at an affordable price. About Portugal beeing 100% renewable for a while. It's very good but it still kinda sucks the reason was that there was weekend and holidays so industry was closed. At the same time lots and lots of rain to replenish the hidro and lots of wind. So yes very good but a loool more needs to be done. Cheers

The battery market is improving but slowly. I was also going to point out that your speed gripe is the hull not the motor. That hull design is extremely inefficient BECAUSE it didn't matter with a 15hp motor and high energy density fuel. That hull is simply wrong for 3hp. An appropriate canoe hull could double your speed and range.

Thanks for taking the time to make this video. I appreciate all your thoughts on the motor. I just started using my new motor and I’d like to know about cleaning and storage. When I take the motor off my dingy I notice that water drains out of a couple holes on the side of the motor, just in front of the propeller. After a few hours or a day of running around, do you rinse off the shaft/propeller unit, or do you go a few days or weeks before cleaning it? Have you done anything else to keep the saltwater from deteriorating the lower unit? Do you feel like the lower unit could just live on a storage bracket and be constantly exposed to salt spray? Thanks again.

Im not sure what is the correct procedure, but I'm sure its not what i do, because i have never cleaned or rinsed the motor 😂 when we are cruising it stays on the dinghy full time, and i raise the dinghy out of the water on the davits every time to prevent growth on the dinghy bottom and motor. When we a not cruising i keep the motor in a locker. I have never cleaned it, but now that you mentioned it i think i will start to do it before storing it. Cheers

If your boat's waterline length is 10 feet your expected hull speed is 4.24 knots, So, to go beyond that speed requires a lot more power to go just a little faster because of the bow wave.

That’s for a displacement hull. Any planing hull reacts quite differently.

The effect you are seeing with speed (velocity) versus power is about right. Drag follows "cubed law." If you need 200 watts, for example, to go 2 knots, you will need 2 X 2 X 2 (8 times) as much power to go 4 knots (assuming hull speed doesn't become a factor). The difference is: a gasoline outboard doesn't have a power meter, so you can't see that effect, but it's there also. It looks like you are doing a little better than the formula says you should, probably because the prop becomes more efficient at higher RPMs.

Yes it is super dumb. It should have an indicator on the battery itself. 5 LED's would have been enough to do the job.

I have a guess here...that RIB is not going up on plane. So can it be considered a full displacement hull when using the electric motor? Optimal hull speed for a 9 foot boat in that case would be 4.02 Knots. That would explain why the sweet spot is 200/250 watts. Trying to push it past hull speed just sucks up more power with very little increase in speed. Again...just a guess.

Hi. It was two and a half hours to charge the 2 bars that we used on the trip. However it seems the charging speed drops as it gets full. Like in electric cars, its 0 to 90 in two hours and then another two from 90 to 100... Seams like ita similar

@Black-March

7 ай бұрын

The way charging works is that the fuller the battery is the slower it needs to go in order to charge safely without damaging the battery. That's why going from 10 to 80% on a phone or outboard or anything is super quick but 80 to 100% takes longer than 10 to 80 did.

Am I understanding this correctly? When on shore there is no means to lock the battery to the rest of the engine so one is forced to either lug 8kg around or risk it being stolen??

Yes, there is no built-in lock. However, you might be able to lock it using a chain and a padlock. Nevertheless, I would not feel comfortable leaving the battery on site even with a training padlock so I just take my battery with me.

I just use a bike lock on mine and it works quite well.

Nobody drives their gasoline outboard at full power, usually only at 60 to 75%. So the Newton meters on the shaft are far from what you imagines. However, an electric motor delivers the full newton meters from first RPM, while the fuel engine can deliver them the newton meters that you can read off at its highest speed. See datasheet. Okay at the highest speed with noise you not like. So is the realität. If you let two identical inflatable boats compete against each other, one with an 1kw electric motor and one with a 1kw fuelmotor, you will realize that the electric motor has already pulled the other inflatable boat away long before it has even made a few revolutions and it will never be able to compete against the electric motor. greetings
