Automatic Submersible Boat Bilge Water Pump 12v 1100gph Auto with Float Switch, 1-1/8" Outlet, Compact Marine Boat Yacht

Working like a champ...solid product at a good/fair price. Bought this one as a backup for the first one we bought last May (2025) that is currently working fine...just wanted a backup in case the first one had a problem while we were camping. NOTE...we are using this in a portable DIY sump plump box for our Anvil cargo trailer toy hauler/camper conversion (aka our Harley Hauler) to plump the water (gray water) from our sink up into the sewer opening at campgrounds that have full-hookups. Due to the cargo trailer conversion being lower to the ground than regular RV camper trailers, it's hard (most times) for the water to drain unless the drain plugs are much lower than the camper pads. I'd buy again in the future and would/will recommend to others.

Works good.

Pros: - Price. Seriously that is a good price for an emergency pump. - Small size and light weight. - Decent GPH for such a small unit. 1100GPH is good but remember it will decrease significantly pumping up. - 12V capability makes it versatile. - Internal float switch. Saves you money. Cons: - The output port is an odd-ball size. I had to make an adapter using Flexible hose just to get it to a standard size. I think they should include some adapters to make this easier on people. (if you plan on using PVC) - Noisy but do you care? I guess that depends on how often it turns on and if you can hear it. - I with the lines were a bit longer. You can splice more line but you gotta seal it very well. - The specs here say 3M head, the book it comes with says 5M, but honestly it has a tough time at 2M. I can hear it really trying hard. I'm not sure how long it may last. We'll see and I will update my review. Based on what I am seeing now, I would recommend this as a backup pump only. BTW: If you have a Watchdog Emergency Sump system and your pump died, this will work as a replacement. You must cut the connector off the old broken pump and splice it to the lines of this pump but IT DOES WORK fine. It's a cheap emergency backup pump! That what I used it for.

Installed on my 18 foot fiberglass deck boat. Moves water quickly. No complaints.

Super powerful. Hooked this up to my boat as a main bilge pump and was impressed with how quickly it can pump water out of the boat. Has lots of pressure. Easy to wire and install too. Can either be hooked up to an on/off switch or has a built in float switch, or you can wire in both!

Quality product that works well! I also had an incident during the warranty period that required a replacement. The company was good to work with in getting me a warranty replacement.

My boat has a factory installed bilge pump that is manually operated. This is fine for people who are day boaters who then trailer their boat home. In my case, I own a lake cottage and the boat is in the water continuously through the summer months. During a hard rain, I want the bilge to be pumped automatically. That's where this pump solved my problem. The factory pump uses a screw in hose, and the Maxzone pump has a barbed exit that required that a hose be pressed on. So, I kept the factory pump and installed the Maxzone. It take a standard 1" plastic hose, which I heated in boiling water and easily press it in place. Once cooled, the hose is held tightly in place on the barb. Then I ran PVC pipe over the transom. I connected the two automatic wires to the terminals of my battery and that completed the installation. I tested it by pouring a couple of buckets of lake water into the bilge and the Maxzone pumped it out automatically. I have the 1100gph model, which pumped the water out at a ferocious rate. Frankly, I could have used the smaller model, but the difference in price was negligible. I am delighted with this pump and the security that it provides me.

I recently installed the Maxzone bilge pump on my boat, and I couldn’t be happier with its performance. The 1100 GPH flow rate is impressive and ensures that my boat stays dry even in rough conditions. The automatic float switch is a game-changer, activating only when needed and saving battery life. The pump is also durable and well-constructed, with a moisture-tight seal and ABS material that gives me confidence in its longevity. Maintenance is a breeze thanks to the detachable strainer base, which makes cleaning quick and easy. While it can be a bit noisy, the peace of mind it provides far outweighs this minor inconvenience. Overall, the Maxzone bilge pump offers excellent value for the money and is a must-have for any boat owner. Highly recommended!

strong pump with a good head of 2mts on our training craft. Auto pump feature is handy as it will automatically start pumping once water enters the space it is in.

Excelente relación calidad precio.

Great product I love the auto on feature. Peace of mind when you’re leaving your boat at the dock for extended periods.

Great product, works just like described

Fast pump. Easy to install
