I upgraded my paddleboard into an "electric submarine"—and the result is absolutely silky smooth!

Honestly, it all started because I just wanted to make paddling my SUP (Stand-Up Paddleboard) a little less exhausting.

I had no idea what I was getting into.

👉 By the time I was done, I had basically created a miniature "electric submarine" experience.

Looking back, the biggest change wasn’t even the speed.

It was this:

The entire on-water experience completely transformed.

At First, I Was Just Tired of Paddling

If you spend any time on a SUP, you already know the deal:

• Going downwind? Absolute paradise.

• Heading into a headwind? A living nightmare.

It gets brutal when you are:

• Going for long-distance cruises

• Loaded down with heavy fishing gear

• Trying to fight the wind to get back across a lake

It will seriously make you question your life choices. One time, I got halfway out on a lake only to realize the entire return trip was a brutal headwind. That final stretch wasn’t exercise anymore—it was pure survival.

That was the exact moment I started researching: Can you actually put a motor on a SUP?

I Thought the DIY Process Would Be a Nightmare

Initially, I pictured the worst: welding, drilling holes into my board, waterproofing mess, and a mountain of complicated DIY work.

But modern systems have completely changed the game.

Things got incredibly easy when I discovered APISQUEEN’s integrated thruster systems (like their U9 or AQ1020 high-efficiency motors with built-in ESCs):

✔ The Electronic Speed Controller (ESC) is built right inside the motor housing—no messy external wiring.

✔ It’s purely plug-and-play.

✔ Installation is way easier than I ever imagined.

It’s actually simpler to set up than most fish finders. You just slide it right into your paddleboard’s fin box, and you're good to go.

What Shocked Me Most Was the Silence

I expected an electric thruster to be loud, sound like a cordless drill, and vibrate like crazy under my feet.

But the first time I dropped it in the water:

👉 It was eerily quiet.

This is where APISQUEEN’s sine-wave FOC (Field-Oriented Control) system shines. When you are cruising at low speeds:

It doesn't feel like you are being "propelled." It feels like you are gliding.

It’s hard to describe because it doesn’t have that mechanical vibe of a traditional trolling motor. It literally feels like the water itself is gently pushing you forward.

The First Time I Hit Full Throttle, I Couldn’t Stop Laughing

The real madness happens when you kick it into mid-to-high speed.

Before this setup: Fighting the wind was painful, long distances were exhausting, and my arms would be burning after 30 minutes.

Now: With the APISQUEEN power kit, I just kick back and cruise effortlessly.

The biggest shift? I used to avoid distant, unexplored areas out of fear of getting tired. Now, I actively seek out the furthest parts of the lake.

Why? Because "I know for a fact I can get back effortlessly, no matter what."

The Ultimate Game-Changer? Fishing.

If you use your SUP for kayak fishing or SUP fishing, adding an electric thruster is a literal cheat code. Here is why:

1. Ghosting right up to the fish

The FOC thruster is practically silent at low speeds. Compared to traditional PWM motors, it has significantly less electrical whine and almost zero vibration. When you are stealthing through shallow water for bass or flats fishing, a noisy motor spooks everything. This setup doesn't.

2. Effortless spot-locking and positioning

Before: I was constantly drifting, frantically grabbing my paddle to correct my course, and trying to manage a fishing rod at the same time.

Now: Using APISQUEEN’s wireless waterproof remote, I can make micro-adjustments or maintain a slow, precise crawl. My hands stay 100% free to cast and fish.

3. Zero return-trip anxiety

This is the ultimate peace of mind. I used to get anxious if I wandered too far out. Now, as long as my battery is charged and my thruster is running, getting home is completely stress-free.

But Let's Be Real: I Made Some Mistakes Early On

It wasn't a perfect setup right out of the box. I definitely fell into a few classic traps.

❌ Mistake 1: Buying a thruster that was way too heavy

At first, I bought a heavy, industrial-grade metal thruster. Big mistake. It made my SUP completely tail-heavy, ruined the tracking, and made it incredibly hard to balance.

I quickly learned that paddleboards require lightweight designs with high power-to-weight ratios. Switching to the APISQUEEN U92 Pro (which is specifically engineered for kayaks and SUPs) fixed everything. It keeps the board perfectly balanced, plus it has a sand-proof and anti-corrosion design, so I don't have to panic if I run into shallow, sandy banks.

❌ Mistake 2: Skimping on the battery

To reduce the burden on myself during my first run, I hastily assembled a small, makeshift battery. While I was having fun, it probably ran for a few minutes, maybe ten minutes at most. Then the battery died, and I spent the next hour anxiously paddling against the wind. Take my advice: stick to a properly paired, high-capacity marine battery kit. True range gives you true freedom.

❌ Mistake 3: A crooked mount

If your thruster is even slightly misaligned, your noise goes up, your thrust feels weird, and your board constantly pulls to one side. Once I used a proper kayak/SUP mounting adapter to align everything perfectly, the performance difference was night and day.

Why I Prefer An Integrated FOC Thruster for My SUP

It’s not that traditional PWM (Pulse Width Modulation) controllers are bad—they are incredibly reliable, budget-friendly, and perfect for raw power. But for a paddleboard, where you sit right above the water and crave that peaceful, quiet cruise, upgrading to an integrated FOC (Field-Oriented Control) system is a total game-changer.

Here is why the FOC integration fits the SUP and fishing lifestyle so perfectly:

When you are out on a glassy, silent lake at dawn, that seamless, near-silent FOC propulsion feels less like a motor and more like a premium upgrade. It’s all about matching the right tech to how you want to experience the water.

What Does It Feel Like Now?

The best way to describe it: "It turned my SUP from a piece of workout gear into a water-bound cruiser."

Before: I used to think, "How far am I willing to paddle today?" (Because it was tiring).

Now: I think, "Where am I going to explore today?" (Because it’s effortless).

The entire hobby has changed for me.

The Verdict

Converting my SUP into an "electric submarine" changed everything. And again, it’s not about turning your board into a speedboat. It’s about:

✔ Ultimate freedom

✔ Zero fatigue

✔ Complete silence

✔ The confidence to explore further

If you love lake cruising, long-distance exploring, or SUP fishing, this is a massive upgrade.

If you’ve been riding a SUP for a while, you're eventually going to ask yourself the same question I did:

"What would it feel like if this board just moved forward on its own?"
