Perfect for camp washes.

The build quality is really impressive; the pump assembly is solid and well put together. This works perfectly for me because I can pull water straight from the creek instead of wasting my freshwater supply. Honestly, it works almost as well as the garden hose back at the house.

Strong water pressure.

Great washdown pump with serious water pressure-something a lot of other units lack...

Alyssa Murray
Very effective.

This is a complete pump kit. You get the pump, filter, fittings, and nozzle. The pump itself feels beefy-you can tell by the weight of the metal housing and the large copper-wound motor. The pressure is easy to adjust via a screw on the top of the housing. Installing the filter and hose connections was a no-brainer. It's got four rubber feet for vibration dampening, which helps keep the noise down. I use it at the dock slip to wash the boat, and the pressure is more than sufficient. The nozzle has a coiled hose and about ten different spray settings to cover any cleaning job. Overall, super happy with this pump. Would definitely recommend.

Great pump, solid pressure!

Awesome budget pump for the RV! It seems like a durable unit. The build quality is solid and the built-in pressure switch helps protect the plumbing. It works exactly as it should. Water pressure is excellent! Plus, it came with a bonus garden hose, which I actually needed. Overall, great value!

12V water pump kit.

The self-priming action and built-in pressure switch make this thing super user-friendly, and the whole install looks really clean once it's tucked away. The noise level is manageable for a pump of this capacity. This kit is a great value for a complete, high-output 12V system. Based on the materials, I expect it to have a long service life with minimal water sitting inside the pump housing.

This pump rocks!

Whether you're running water, antifreeze, or whatever else, this unit delivers killer flow and really strong pressure. It auto-shuts off when pressure builds up, which is a nice touch you don't usually see at this price point. I also built a transfer setup to move water from a storage tank to my RV, and this pump handled 100 gallons at a time without breaking a sweat. Multiple cycles and zero issues. Setup was simple and it runs surprisingly quiet. This thing is a rockstar. I'd absolutely recommend it for RVs, off-grid setups, liquid transfer, or any job where you need a reliable little workhorse that punches way above its price tag.

Love this pump!

I really like the 80 psi pressure on this pump-it's perfect for general washdown tasks. The kit came with everything I needed: all the adapters, a coiled hose with multiple spray patterns, a strainer, quick disconnects, and hose clamps. The built-in pressure switch is a great feature for maintaining steady flow. It wasn't overly loud during testing, but honestly, the ability to hold pressure is what matters most for cleaning. The components feel well-made and the assembly is solid; this seems like a reliable piece of gear.

Great pump.

I've tried a bunch of ways to keep feet and toys clean on the pontoon boat, and most setups failed miserably. I'm stoked to get this system installed this year so I can have a legit hose to spray off sand from paddleboards and the kids before they track it all back on deck. I'm planning to run this pump off an onboard tank with a freshwater fill inlet so I can hose things down whether I'm in the water or on the trailer. I've used a few things from this brand before, and the quality is always solid-good paint and coating, thick plastics, and threads that actually mate up tight.

Looks well built.

Seems robust. No complaints so far. It moves a ton of water for landscaping work. I'm putting it through its paces.

Evelyn Martin
Love the pressure boost!

I'm really pleased with this product. I installed it on my boat and it performs flawlessly. The water pressure makes washing down and rinsing gear quick and painless.

12V washdown pump kit.

This is a 12V DC washdown pump kit. The pump is rated for up to 7.5 GPM at 80 PSI. It's a 5-chamber self-priming diaphragm pump with a pressure switch. Just hook it up to any 12V power source and you're in business. It's ideal for washing down boats, RVs, solar panels, you name it. We've got everything but the boat, ha! Great value for the money.

Noah Jones
Awesome washdown kit.

This is an awesome setup-way more than just a pump. It has everything I need to clean up the boat after a day on the lake. Since it runs on 12V, I just hook it up to my trolling motor battery. It's perfect for cleaning down the hull to prevent the spread of Aquatic Invasive Species (AIS), which my state has really started cracking down on. Great value for the price, and the pump itself is a little beast. Strong motor and solid pressure from the spray nozzle for cleaning.

Mason Hernandez
Money well spent.

This pump is ready to go right out of the box-it includes just about everything for the install. It's clearly a quality product. It even comes with a coiled hose and a sprayer/wand, which is great for rinsing off whatever you need. For the asking price, the value is incredible!

Good freshwater pump.

I was in the middle of rebuilding a boat and had space for an extra tank, so I needed a pump. I already had a raw water washdown installed, but I wanted a source for clean, clear water. This kit had everything I needed except the supply hose and a couple of tank fittings. Once I primed it initially, it was good to go. It pushes serious pressure and will empty a tank faster than you'd think if you're not careful. The built-in strainer is a huge plus for keeping sand and grit out, especially if you're using it for raw water. It doesn't seem to draw much power and it's fairly quiet. Quality is on par with what you'd find at a local marine store, but you get all the install hardware included. Works great-it's a luxury having fresh water for cooking and cleanup on the water.

E
Emily White
Reliable and powerful.

Replacing the old OEM pump was pretty straightforward, but more importantly, this thing handles the increased pressure like a champ! It's great for washing blood off the deck after a fishing trip!

Aiden Jackson
Install was a breeze.

Absolutely fantastic. Works perfectly. Installation was straightforward. The pump itself looks and feels like a high-quality piece of equipment. If you're on the fence about buying one, just pull the trigger.

Logan Gonzalez
Absolutely fantastic.

Best bang for your buck right here. This pump works great for my garden irrigation. The pressure is just right and the flow rate is plenty. Very satisfied.

Isabella Lopez
Does exactly what I need.

I deal with really hard water that leaves nasty spots on the car, so I wanted to use condensate water from my HVAC system. Paired with a 40-gallon drum, this pump does exactly what I needed. It runs relatively quiet and provides solid pressure. It also came with a good assortment of accessories.

H
Harper Moore
Running great so far.

Perfect washdown pump for the boat! The pressure is just right for hosing down the deck. I just upgraded the wiring to a 30-amp breaker on the distribution panel and it's been working like a champ!

C
Charlotte Thomas
Runs smooth.

I'm using this as a transfer pump from my rain barrels to level them out when one gets too full. I've got it hooked up to a smart home sensor and integration, and it works flawlessly. It provides plenty of pressure for my drip irrigation system, which is exactly what I bought it for.

B
Benjamin Taylor
Works flawlessly.

This thing is awesome. I was looking for something to put on a 250-gallon fish tank setup. I love that it's always primed and ready to go. I've got it wired into my solar system, too. It fills fast with no air bubbles, and it's surprisingly quiet. You can hear it running, but it's not a distracting noise at all.

Mariah Blake
Solid kit.

A solid kit with pretty much everything you could possibly need included. I have mine mounted on a cart with a 35-gallon tank. I power it with a LiPo battery. Works like a charm!!

L
Liam Williams
Works well for me.

This pump kit is built well and is a lifesaver when 12V DC is your only power option. They call it a "kit" for a reason-it includes the pump, a coiled hose, spray nozzle, debris strainer, and a whole assortment of fittings and clamps. I'm really happy with it. I plan on using it to water and fertilize plants and the lawn on a property that's off-grid with no water or electric hookups.

Teagan Pierce
Easy to use, works great!

The Kohree 12V DC washdown pump kit was a breeze to install and works like a charm. It's compact, dependable, and puts out excellent pressure-super portable for traveling. The kit is pretty much turnkey; it comes with everything you need to get up and running. I use it to rinse off my boat and it handles the job flawlessly, whether in fresh or saltwater. Overall, it feels well-engineered and quality-built. Definitely a solid bang for your buck. Highly recommend!

FAQs About 7.5 GPM Washdown Pump Kit 80 PSI 12V for Marine & RV

Absolutely. Delivering 7.5 gallons per minute (GPM) at 80 PSI, this pump provides high-flow, high-pressure cleaning power. This is significantly more output than many standard washdown systems, making it highly effective at blasting away stubborn salt, mud, fish slime, and debris from decks, hulls, and anchor chains, drastically reducing your cleaning time.

Traditional diaphragm pumps often have fewer chambers (like 3 or 4). This pump's 5-chamber design​ means it has five independent pumping diaphragms working in sequence. This results in smoother, more consistent water flow​ with less pulsation and pressure fluctuation compared to pumps with fewer chambers, providing a steadier, more powerful spray.

Yes, the kit includes a seawater filter, which is essential for raw water applications. You can plumb the pump's inlet (using the included barbed fittings) to pull water directly from a through-hull fitting, your bilge, or a dedicated washdown tank. The filter protects the pump from debris that could cause damage.
