Electric outboard reviews and real-world tests
We didn't make these videos. Boaters, dealers and YouTubers did, on their own boats and in their own words, racing the Momentum M10 against gas, living with it on a tender, and putting the U2 through its paces. That makes this the closest thing we have to an independent set of Momentum Electric Marine reviews. If you're reading electric boat reviews to figure out how an electric outboard holds up off the spec sheet, start here.

Key takeaways
- Gas vs electric: in David Shih's two-week test against a Tohatsu 20HP, the M10 got on plane faster and won the tug-of-war, while the gas motor was about 1 mph quicker at the top end and still wins on range per tank and upfront price.
- Stepping up from 6 kW: on the same 15 ft Glastron, Wayne The Boat Guy measured about 7.5 mph with an ePropulsion Navy 6 and about 14.5 mph with the M10.
- Range depends on how you drive: the Wynns covered just over 17 nautical miles in about 6 hours at an average of around 5.5 knots on one outing. Your numbers will differ, so try the range calculator with your own boat.
- Working boats, not just toys: Fulham Reach Boat Club on the Thames now runs 60% of its coaching fleet on electric, with Momentum M10s on daily support duty.
- U2 for small tenders: reviewers like its light weight and removable battery, and EMO Electric's review is upfront about what they'd still like improved.

Featured tests
Can Electric Actually Beat Gas?
David spent two weeks testing a Momentum M10 and MB-6 battery against a Tohatsu 20HP four-stroke on identical Mantus 104 dinghies, covering weight and balance, time to plane, a quarter-mile race, tug-of-war, charging, range and cost. In his runs the Tohatsu topped out around 18 to 18.5 mph with the M10 about 1 mph behind, while the M10 got on plane faster and won the tug-of-war. He's upfront that gas still wins on raw range and upfront price.
My boat was too slow
Wayne repowers his Vision Marine Phantom from an ePropulsion Navy 6, which he says topped out around 7.2 to 7.3 mph, to a Momentum M10 and MB-6 battery he had in the garage. He walks through pulling the old motor, battery and controls, routing the M10 power cable and mounting the display, then heads out for a first test on the water.
We Take Our Tiny Boat As Far As We Can
Hiding from the wind on England's River Dart, Jason and Nikki take their electric tender as far upriver as the battery and the tide allow. Along the way they show the cruise lock, the speed governor and the button that unlocks full power. Their tally at the end: just over 17 nautical miles in about 6 hours, averaging around 5.5 knots, with current against them for parts of both legs.

Electric Outboards: Momentum M10 vs ePropulsion Navy 6 top speed test!
Same boat, two motors. Wayne runs his 15 ft Glastron with an ePropulsion Navy 6 and then with a long-shaft M10 on remote steering. On his phone GPS the Navy 6 peaked around 7.5 to 7.7 mph, while the M10 reached about 14.5 mph and started to bring the boat onto plane. He notes the M10 is louder, and says he likes both motors.
Spirit 2 vs Momentum U2: Battery Installation
A one-minute how-to from EMO Electric showing how the battery comes off and goes back on the ePropulsion Spirit 2 and the Momentum U2. On the U2 you squeeze two blue tabs and lift, then slide it back down until it clicks.
The Electric myth: Just Got SMASHED. The Outboard with answers!
Chris from Sail Hub heads out of Lymington in the UK with Algie from Electric Outboard to see whether the M10 changes his mind about electric outboards. With two people aboard a small RIB it goes from about 3 knots to around 15 knots on plane, and the second half is a Q&A on the battery, its reserve and charging.
...AND WHO SAID ELECTRIC SUCKS?
William and Jana from Sailing Dawn Hunters fit an M10 with its 72 V battery to the aluminium dinghy for their catamaran. They show the throttle, instant forward and reverse, cruise control and the on-screen range estimate, and share first impressions after their early runs.
A PLANING Electric Outboard?! Testing out the Momentum M10
Luke from EMO Electric takes the M10 out on a Further Customs dinghy and gets it on plane comfortably, reading speed and remaining range off the built-in display; the display showed about 16 to 17 knots at full throttle. The second half is a walkthrough and Q&A with Leonard from Momentum USA on the battery and its reserve, the single-cable hookup, the boost button and third-party batteries.
I Tried the NEW Momentum M10 Electric Outboard Motor and It Was WILD!
Wayne's first look at the M10, on a 150 lb, 13 ft wooden skiff rated for 3 hp. He shows the four main parts (motor, transom bracket, 72 V MB-6 battery and the long power cable), how the motor clicks onto the bracket, and the red button that unlocks full power. His take: it's too much motor for that skiff and better suited to his Glastron.
One Design Problem Is Limiting Our Entire Boat
Not a motor review. The Wynns explain why neither the crane nor the stern davits on their 50 ft explorer yacht were engineered to carry a tender, and how that puts their dinghy upgrade on hold. The outboard isn't discussed by name, so watch it for the liveaboard tender story rather than motor details.
We Invited a Family to Live on Our Boat for a Month
Jason and Nikki host a family of four aboard for a month, which means a lot more tender runs ashore. They show the Momentum M10 they chose because it can move over to a new tender, run with a spare battery, and explain the half-throttle limit with a button for full power.
This Is Not the England We Expected
Fossils, white cliffs and quiet anchorages along England's south coast, with plenty of dinghy trips ashore. The tender shows up throughout, but the motor itself isn't a focus of this episode.
Inside Our 50ft Aluminum Explorer Yacht
A full tour of UNDRA, the Wynns' 50 ft aluminum explorer yacht. In the tender section they show their Momentum M10 and its two batteries, which they hadn't fitted yet while working out how to carry the tender.
Two Days on an OffGrid Condomaran: Life Aboard our Royal Cape Hybrid Catamaran
Two days aboard a Royal Cape hybrid catamaran, one at anchor and one underway, focused on how the owners make, store and use power. Their 14 ft inflatable dinghy runs twin 10 kW electric motors, which they say plane it at about 17 mph, and it charges from the boat's own power system. The video doesn't name the motor brand.
1952 Cedar Strip Boat Goes Electric: Momentum M10 Owner Review
Andrew swapped a smoky 1972 Mercury two-stroke on his 1952 Peterborough cedar strip runabout for an M10 with remote throttle, and installed it himself. M-Oceans joins him at the Island Yacht Club in Toronto, where he talks through the steering hookup, the strong low-speed torque and the range readout, and the boat reaches about 23 knots at full throttle.
The Momentum U2 is HERE! Full Review & Sea Trial (2.5kW / 5HP Electric Outboard)
EMO Electric's full review of the 2.5 kW U2: what's in the box, weight (they put the motor, battery and bracket at roughly 40 to 42 lb combined), installation, tilt, the tiller, display and charging, plus a range and runtime test on the water. They also flag what they'd like improved, such as a cap for the battery-side pins and a longer shaft option.
Three Momentum electric outboards, dinghy to workboat
A 16-second short from Electrified Marina showing Momentum battery accessories: a third-party 72 V battery adapter and the connection for running two MB-6 batteries.
Yes, that's a Momentum U2 completely underwater
A short from Electrified Marina of a U2 running fully submerged in a demo tank at the Momentum booth in Cannes, France. It's a display, not a test on open water. The description points to the sealed battery, IP-rated connectors and passive seawater cooling.
Aspen Carbon Cat Introduces M10 Electric Outboard
Larry from Aspen Power Catamarans walks through the M10 on an Aspen Carbon Cat T11: motor and battery weights, the throttle, the reverse and boost buttons, and the magnetic kill switch, before taking it out for a few runs.
Momentum M10 powered electric safety boat for Fulham Reach Boat Club
Adam Freeman-Pask of Fulham Reach Boat Club on the Thames explains why the club moved its rowing support boats from a Torqeedo tiller setup to Momentum M10s. He says the M10s have stood up to daily use on a tough tidal foreshore, and with a third boat now in service, 60% of the coaching fleet is electric.
Ηλεκτρική εξωλέμβια Momentum U2 (Momentum U2 electric outboard)
Giorgos from Greek dealer Loukianos Boats tries the U2 on a small inflatable tender. He covers the 2,500 W motor and the removable battery you can swap out for more range, and calls it quiet, light and a good fit for short tender runs. In Greek.

Questions buyers ask
Is an electric outboard as fast as a 20HP gas outboard?
It depends on the boat and the load, so treat any single test as one data point. In David Shih's side-by-side on identical dinghies, a Tohatsu 20HP topped out around 18 to 18.5 mph and the 10 kW Momentum M10 ran about 1 mph behind, while the M10 got on plane faster and won the tug-of-war. Gas still carries more range per tank, which he points out too.
How far can a Momentum M10 go on one battery?
Range changes a lot with speed, hull, load and conditions, so we don't quote one number. The MB-6 battery is rated at 6.4 kWh, with about 5.5 kWh usable and the rest held as a reserve. The M10 display shows a live range estimate at your current speed, and our free range calculator at electric-marine.com/battery-calculator/ lets you plug in your own boat.
How does the M10 compare with the ePropulsion Navy 6?
The M10 is a 10 kW motor and the Navy 6 is 6 kW. Wayne The Boat Guy ran both on the same 15 ft Glastron and measured about 7.5 to 7.7 mph with the Navy 6 and about 14.5 mph with the M10, noting the M10 was louder. He later repowered a second boat from a Navy 6 to an M10. Both of those videos are with the other M10 reviews in the list above.
Is the Momentum U2 a good motor for a dinghy or tender?
The U2 is a 2.5 kW outboard with a detachable battery that slides on top of the shaft, and the motor, battery and transom bracket come apart for carrying. EMO Electric's review covers installation, runtime and the shaft lengths to pick for a dinghy, so it's a good one to watch before you choose.
Can I use a Momentum outboard in saltwater?
Yes, and several of the boats in these videos run in saltwater. Electrified Marina filmed a U2 running fully submerged in a demo tank at the Momentum booth in Cannes, France, and the connectors are designed to seal when mated. Like any marine electrics, rinse with fresh water after use and make sure the pins are clean and dry before you connect them.
