SEAFLO 01 Series 350 GPH Bilge Pump – 12V, 3/4" Outlet, Marine Submersible Pump with Anti-Airlock Protection, CE & Rohs Certified, 4-Year Warranty | Reliable for Boats and Marine Applications

Professional install. Works great.

Bought a used bass boat recently and have been going through the boat, getting it ready for the water and I find everything working fine, butmy bilge was manual switched on only. Now, if I'm just having the boat in the water while using it, that's fine, but, intend to have this docked on the lake, so when unattended, I have that security knowkñg if the boat does happen to start taking on water in my absence, well, I won't arrive to mooring ropes hanging off the side of the dock with a submerged boat down there. The other side feature with this auto pump, is that it is a three wire setup. Meaning. One continuous hot(or ON thru an on/off/ on switch) and, full auto function wired with fuse to constant switched power on the other side of that on/off/on switch on the dash. Nice thing is, my manual switch pump was already pre wired in the boat. And it still works, so I extracted it for later use, then with its existing wiring, easily wired for the fully auto function, then just simply crimp on your different colored wire for that manually switched side, crimp on a good waterproof fuse block and connect that to the other side of the switch, which was also swapped out from an on/ off to an on/off/ on switch, put the little rubber switch cover on, and I'm done. Fully functional, more reliable insurance. The best feature I noticed really is that, if the boat is trailered, I can simply turn the switch to off, and have no live wires back there in the transom and sump, incidently where a 15 gallon fuel cell rests also. I already know this brand and trust it already, it's a no brainer. Oh, and at 750 gal/h, the pump rating? Unless someone took a Browning BAR to your hull? It pumps the water out plenty fast, battery health is your only other concern there.

I purchased this bilge pump for my 1986 basstracker bass boat it works good for a small boat. Compact makes it user-friendly in just about any location. It's quite and pumps out pretty quickly.

excellent performance

EDIT: The original unit broke after a short time and the seller promptly replaced it. I have not had a chance to test the replacement yet but it's great that the seller has prompt customer service. This is my original review: I was looking at a competing brand that supposedly is made in the USA , but that one had really poor documentation with flow charts in Chinese units. This one is made in China but it actually comes with good documentation in English including flow charts. Good product for half the price. A few installation tips: 1) If you use this with a check valve, drill a small 1/16" hole before the check valve so the air can get out. Otherwise if you suck any air, a pocket of air can get trapped before the check valve and then the pump won't prime. 2) with 10' cables and a standard battery I wasn't quite getting enough head pressure so I bumped up the voltage with a separate power supply. You can get more pressure with more voltage 3) This unit does need to be level for the float to work reliably. Initially I had mine just attached to the hose which kept it in place just fine but it wasn't quite level, and the float would hang up. Sometimes it would fail to turn on and sometimes it would fail to turn off. I got a piece of hardy board that doesn't rot and screwed the pump to that, and that fixed it. Good product, been in use for a month orso now. I got this after my old pump did not draw down the water low enough. This one draws it down nice and low, maybe 1-2".

1/3 price of Rules 2000gph that people are saying are NOT as Good as They once were.......10 times more flow than the old one and they DO go bad and worked intermittently as it failed, boooo hissss but now I now and will replace every few years as flow diminishes!!!!!!!!!

I bought the SEAFLO 01 Series 1100 GPH Bilge Pump for my 18-foot fishing boat after my old one quit on me. I had a much more expensive bilge pump before that looked pretty similar, and I was happy to see this one fit right into the old bilge housing with no issues. It saved me a lot of hassle since I didn’t have to mess with new mounting or brackets. This pump works great so far. It moves water out fast, and I’ve had no problems with it clogging or airlocking, which was an issue with my last pump. I took the boat out on the lake for a full day, and the bilge stayed nice and dry, even with some choppy water splashing in. The 1-1/8 inch outlet matched my setup perfectly, and I like that it’s submersible and has a 4-year warranty. It feels sturdy enough for regular use, and I haven’t noticed any leaks or weird noises. One thing I’d say is to double-check your wiring setup. I had to trim the wires a bit to fit my existing connections, but it wasn’t a big deal. Also, it’s a little louder than my old pump, but not enough to bother me. For the price, this is a great deal compared to the pricey one I replaced. It does the job just as well, and I’m glad I didn’t have to modify anything to make it fit. Definitely recommend it if you need a reliable bilge pump for your boat.

This is a good little bilge pump to handle general light water ingress. While with 3-4 foot of head the volume is noticeably decreased but that was suspected. As a note, the 1 1/8” hose specification is only to fit over the ridges of the hose barbs but you really need a 1” I.D. hose to actually fit snugly and to be able to seal up with a hose clamp. The wires are rather short so you will likely need to lengthen them as needed based on your installation. These float switch works well although expect about an inch of water to remain when it shuts off. I was not able to test actual current draw, but for my initial purchase a garden tractor battery ran it extremely well for about 15 minutes without killing the battery so a marine battery should be more capable over longer periods of time.
