Stand-up paddleboarding is one of the simplest joys on the water — just you, your board, and the rhythm of paddling. But wind, current, or tired muscles can quickly cut your adventure short. That’s why more paddlers are turning to electric SUP motors: compact, easy-to-use upgrades that give you an extra boost.
If you’re looking for the best options under $600, here’s our top 5 list — with Boost Fin standing out as the most balanced and versatile choice.

Why Boost Fin Leads the Pack
Boost Fin isn’t just another electric motor kit — it’s a purpose-built upgrade for SUPs, surfboards, and even kayaks. Instead of bulky batteries or complicated mounts, it looks and installs just like a regular fin. Slide it in, secure it with the included adapter, and you’re ready to ride.
• Runtime: Up to 100 minutes — perfect for most paddleboard sessions, which usually last 60–90 minutes.
• Compatibility: Works with US Box, Slide-In, and kayak mounts.
• Ease of Use: Wireless remote control, instant response.
• Weight: Lightweight design, no heavy battery packs on deck.
• Price: Around $599 — affordable compared to bulkier systems.
It’s powerful enough for surfers to catch waves, but simple enough for beginners or families. Boost Fin gives you freedom without complexity.

Other Options Under $600
1. PowerFin 4-Speed Electric Paddle Board Motor Package
The PowerFin is one of the few full kits available under $600. It comes with a motor, waterproof battery pack, wireless remote, charger, kill switch, and adapters for US Box and Slide-In.
• Thrust & Use: Delivers solid push for cruising.
• Runtime: Up to ~80 minutes at full power, longer at lower speeds.
• Weight: Around 10 lbs combined (battery 5.5 lbs, motor 3.25 lbs).
• Mounting: Requires installing the separate battery on deck.
Verdict: A good all-in-one package, but bulkier than Boost Fin.

2. Paradise Pad Electric Motorized Fin Kit
AThis kit integrates the motor into a fin-style design and claims impressive runtimes.
• Top Speed: Up to 5 mph.
• Runtime: Up to 6 hours on low power (real-world usage will be shorter at higher speeds).
• Battery: A separate 12Ah pack that sits on deck.
• Mounting: Fits into standard fin boxes (Air7 / center fin slot).
Verdict: Sleek design and long runtimes at low settings, but less practical for average sessions compared to Boost Fin’s balanced approach.

3. Haswing Osapian W-20 (Adapted for SUP)
The Osapian is actually a small trolling motor, adapted by some riders for SUP.
• Thrust: 20 lbs, plenty of push.
• Setup: Requires mounts, wiring, and large batteries.
• Drawback: Heavy and not SUP-specific.
Verdict: Powerful, but overkill for most paddleboarders and inconvenient compared to simple fin systems.

4. DIY Motor Setups
Enthusiasts sometimes build their own setups with brushless motors and waterproof housings.
• Pros: Customizable, can be cheaper.
• Cons: Safety risks, waterproofing issues, and no guarantee of reliability.
Verdict: Fun for tinkerers, but not ideal for everyday paddlers.
Why Boost Fin Wins
Competitors may advertise longer runtimes (two hours or more), but most paddling sessions last 60–90 minutes. Boost Fin matches this perfectly, offering just the right amount of power without unnecessary bulk.
It’s also the most user-friendly option on this list: no extra deck batteries, no complicated wiring, and no need to be a DIY expert. It’s as easy as swapping your fin, but with up to 20 lbs of extra thrust at the push of a button.
Boost Fin isn’t just about convenience — it’s about accessibility. Whether you’re a beginner learning balance, an older paddler wanting longer sessions, or a surfer chasing waves, Boost Fin enhances your ride without changing the core SUP experience.
