750GPH Automatic Submersible Small Boat Bilge Water Pump with Float Switch 3/4 inch (19mm) Outlet Diameter Hose

Works great. Delivered fast.

Pump failed and has dead short after one season of use, don't waste your money

This is a great product at an affordable price. However, the industry standard for connecting these (for the auto mode) is to use the brown wire as +ve and black wire as -ve and if you aren't using manual mode, seal and tie off the brown-white wire. When I connected it for auto mode as documented in their manual and as described above, it ran continuously. For a moment, I thought the float switch wasn't working properly but I read someone else's review who indicated that the brown and brown-white wire functions were improperly reversed. After switching these two, my bilge worked correctly in auto mode.

Walker Bay 8' dinghy. It was a pain in the butt always bailing the dinghy. I secured this pump behind the middle seat in the trough. Hooked it up to a motorcycle battery that's bungied under the seat. Drilled the exhaust hose out the starboard side near seat and hooked up a small solar panel. There is a very little bit of rain water in the trough to sponge up but that's it. This pump is powerful and has operated flawlessly for over a year. This setup is maintenance free. UPDATE: It died!!!...got over a year out of it. It did well and Im happy with it's performance. 5 Stars.

The bilge pump came on time the ski still getting work done but as soon as ready will let you know so far it good!! Thank you for the quick response

Bought a few of these as a cheap insurance policy for my jet skis. Having watched a friends have a seal fail out on the water, this would have saved him. Hopefully I never see it come on, but if it does, it’ll not only alert me to a problem, but keep the engine from going under water.

Disclaimer: my use is not for a boat's bilge. I picked up a couple because I needed pumps with float switches to use as drain pumps for indoor garden runoff. If you're into boating then the design is probably familiar. If you are not then be sure that you understand what you are getting. This is a basic water pump with integrated float switch. This pump does not include a power supply. It does not have a barrel connector, just bare wires. It requires 12V 3A power. It is designed to use a three-pole switch, although just for switching automatic mode to manual so this can be bypassed if you're comfortable with making your own alternate wiring config. I used a barrel connector with terminals and a three-pole switch to complete the wiring and connected a 12V 5A power supply that I picked up here. I had tried a 12V 1A power supply that I had, but it just made the pump make noise, so be sure that your power supply is sufficiently rated. So far, I've only opened one pump as I was waiting to get the first working as expected to replicate config on the other. However, I'll probably be abandoning this config because the pump float switch is unreliable. When the water level drops down too far for the pump to continue pushing, it often continues to churn noisily until I reach down and tweak the "test" knob, which is just a knob connected to the float switch to force it to move. Once I turn it far enough for the pump to go off, it stays off. Not recommended due to insufficient reliability for unsupervised operations, with the above disclaimer in mind. Perhaps something about being mounted in a bilge would make it far more reliable, but I cannot trust it when mounted in a pan on a concrete floor. I'll keep them around as emergency supplements for my sump pump or something since they are pretty good at pumping.

I have using that pumps to collect rain warer in my gardening applicants during last season. The pumps are powered by 12v solar panel and 35ah battery. All worked fine. Also I applied additional filter (plastic greed with 1 mm cells) to the pump bottom to prevent from sand etc.

I've only used this a few times so far, but it's been working well. It seems very similar to other bilge pumps I've purchased on Amazon. It moves water quickly and the float switch has worked as expected. Time will tell how it holds up long term, but my initial impression is positive.

fast

The pump works but the instructions should say that the attached hose should NOT be in the water. I left my boat and during windy, wavy weather, the hose ended up in the water and the pump started pumping water INTO the boat. Thank goodness the battery died or my tin boat could have sank!!!!

High value. Double the volume and half the price as OEM bilge pump on a Boston Whaler Montauk 150. Won’t plug with pine needles burning fuse so lasts several seasons.

this bilge pump failed on second fishing trip . the motor impeller became hard to turn and kept blowing fuses . no debris in bilge or around impeller shaft . suspect a poor product . beware .
