Four electric paddle board motors compared on power output, battery life and weight, each with a spec table and a buying checklist.
Every motor in this list is in stock on Amazon right now, and every figure below comes from the manufacturer. The field runs from a 190 dollar fin kit that needs your own battery to a 450 watt fin with a 36 volt pack in the box, so the first question is not which one is best but whether you want a finished kit or a motor you power yourself.
Electric paddle board motors: the four picks at a glance
An electric paddle board motor is either an electric fin that slides into your existing fin box, or a scooter that clamps to the board and pushes from below. The fin is tidier and steers with the board. The scooter comes off in seconds and goes in a bag. Both are judged on the same three numbers: motor power, thrust and how long the battery lasts at a useful speed.
Below you get the short version first: three picks for the most common cases, then the full table with all four, then every motor in detail with specs, strengths and weaknesses.

The four electric paddle board motors in detail
- Motor450W
- System voltage36V
- Battery13,000 mAh lithium, included
- Runtimeup to 10 hours on speed 1, 120 minutes at 6 mph
- Speedsfour forward, remote with plus, minus and stop
- In the boxfin, battery box, charger, Bluetooth remote with wrist strap, two fin box fittings, ankle leash, mounting cords
Best for: Paddlers who want one box that contains everything and a fin that installs in minutes
The Efin is the complete kit. You get the fin, the 36 volt battery in its box, the charger, an IP67 Bluetooth remote on a wrist strap, two fin box fittings, mounting cords and an ankle leash that cuts power when it pulls. Installation is the same motion as fitting a normal fin, and Paradise Pad puts it at five minutes on a hardboard, an inflatable or a kayak.
The numbers behind it are the reason it leads this list. A 450 watt motor on a 36 volt system is roughly double what a typical electric fin runs, and the 13,000 mAh pack is sized to match: up to ten hours on the first of four speeds, or two hours at six miles per hour. That is the difference between a motor that gets you home against the wind and one you can leave running all afternoon.
Pros
- 450W on a 36V system is the strongest complete kit here, and most electric fins stop at 150W on 12 to 24 volts
- A 13,000 mAh pack that runs up to 10 hours on the lowest speed turns this into a touring aid rather than a rescue motor
- Two fin box adapters are in the box, so hardboards, inflatables and kayaks are all covered
- The ankle leash acts as a kill switch, which is the safety feature that matters when you come off the board
Cons
- The most expensive motor in this list
- The 120 minute figure is for the lowest of the useful speeds, so plan on less at full throttle
- Check your fin box shape against the two supplied adapters before ordering, not every board fits
- Motor400W brushless underwater thruster
- Thrust10 kg, about 22 lbs
- Top speed9.6 km/h, about 6 mph
- Weight1535 g
- Mount9 inch tool-free quick-release fin
- Remotewireless, shows voltage, current, battery level and speed
- Batterynot included, takes 19 to 25V packs
Best for: Paddlers who already own lithium packs and want the most thrust for the money
The K4C is the motor for people who are comfortable supplying their own power. It is a 400 watt brushless thruster on a nine inch quick-release fin, it weighs 1535 grams, and it puts out ten kilograms of thrust for a top speed of six miles per hour. Nothing else here publishes a higher thrust number.
The efficiency claim is the more interesting one. Buddy RC puts a comfortable cruise at five to six kilometers per hour on about 100 watts, which means a small battery goes a long way if you are not racing. The remote backs that up by displaying voltage, current, charge and speed while you paddle, so you can watch the pack rather than guess. The trade is obvious: no battery is included, and choosing one is now your job.
Pros
- 22 pounds of thrust is the highest published figure in this list
- At a cruise of 5 to 6 km/h it draws only about 100 watts, so a modest pack lasts a long time
- The remote shows voltage, current, charge and speed in real time, which no other remote here does
- Tool-free quick release means the fin comes off between sessions without a screwdriver
Cons
- No battery in the box, so the real price is higher than the listing suggests
- You are responsible for choosing and wiring a safe 19 to 25V pack
- Cruise control and forward and reverse are useful but add buttons to learn on the water
- Typeunderwater sea scooter with a slide-in SUP bracket
- Thrust14.33 lbs
- Weight3 lbs
- Size14.84 x 2.75 x 2.75 in
- Battery98 Wh, 56 minutes of cruising, 1.2 hour charge at 100W
- Extras100W reverse charging for phones, three speeds and cruise mode
- In the boxmain unit, slide-in fin box bracket, wired thumb controller, propeller pin, screws, spare O-rings
Best for: Travelers, and anyone who swaps the motor between a board, a kayak and a body board
The Subnado is not an electric fin, it is a sea scooter with a bracket that slides into a SUP fin box. That makes it the most flexible thing in this list: pull it off the board and it drives a body board, a kayak or you, underwater, and then it goes back into a bag.
Its case is portability. Three pounds, roughly the size of a small bottle, and a 98 Wh battery chosen to fall under normal airline carry-on rules. Charging takes 1.2 hours at 100 watts, and the same 100 watt circuit works in reverse to charge a phone. What you pay for that is stamina: 14.33 pounds of thrust and 56 minutes of cruising is enough for play and for getting back across a bay, not for a long assisted tour.
Pros
- Three pounds and the size of a small bottle, so it goes in carry-on luggage rather than a car boot
- A 98 Wh battery is under the usual airline limit, which is the whole point of this design
- Charges in 1.2 hours at 100W, fast enough to top up over lunch
- Works as a 100W power bank for a phone or a GPS, so it is not dead weight off the water
Cons
- 14.33 lbs of thrust is the lowest of the three motors here that publish a figure
- 56 minutes is a short session next to the fin kits
- The wired thumb controller has to be clipped to the board, which is one more cord on deck
- Typemotor unit that bolts onto your own fin
- Top speed1 to 3 mph on a 3s pack, 2 to 4 mph on a 4s pack
- Batterynot included, 10 L waterproof bag supplied
- Remotewaterproof wireless, wristband, on and off
- In the boxmotor, battery bag, remote, carabiners, two straps, drill bit and wrenches
- Buildsealed for saltwater, rated for over 5000 hours
Best for: Paddlers who want upstream and upwind help on a budget, and do not mind drilling their own fin
The CuttleJet Mini V2 is the cheapest honest way to find out whether a powered fin suits how you paddle. It is a sealed motor that bolts through your existing fin using the drill bit and wrenches in the box, plus a 10 liter waterproof battery bag that clips to a leash plug or a handle.
Speed depends on what you feed it: one to three miles per hour on an 11 volt 3s pack, two to four on a 15 volt 4s. That is assistance rather than propulsion, which is exactly what you want for paddling upstream, holding position in wind or getting out to a break. Two things to accept going in: the battery is a separate purchase, and drilling the fin is permanent, so use a spare fin if you have one.
Pros
- Far cheaper than every other motor here, roughly a third of the price of the complete kits
- The 10 L bag holds several spare packs, so range is a question of how many batteries you carry
- The motor is sealed for saltwater and rated for over 5000 hours of use
- Fits any SUP, surfboard or kayak fin rather than a specific fin box standard
Cons
- No battery included, and the speed you get depends entirely on which pack you buy
- Installation means drilling your own fin with the supplied bit, which is not reversible
- The remote is on and off only, with no speed control on the water
