Review of the Seaflo Non-Automatic Submersible Bilge Pump


What's up everybody it's AJ with etrailer.com. Today we'll be checking out this bilge pump from Seaflo. And this works at 500 gallons per hour, and what this does is it gets that excess water out of your boat. You probably already have one, you're going to replace it, but if you don't know what it does, let me just show you right now. You can turn it on, put it in the water and that's going to help you out if you leave your boat out at the marina, uncovered, it rains, it gets full of water, it weighs down the boat a little bit, or you just cast your boat out and you forgot to put the plug back in and it starts getting water filling it up. These bilge pumps could help keep up with that and get that water out, that way you don't sink your boat.This bilge pump works with a hose with an interior dimension of three-quarter inches, so that's going to just fit on there, nice and easy.

It does not include the hose that you work with though, so if you're replacing one, you could just use the existing hose on your boat already, and probably the clamp that's on the end. If you're not replacing one, you're adding one, you're going to want to get your own hose and hose clamps.Now there's a couple of different kinds of bilge pumps. This one is what I call a switch base one, when you wire it up to your switch, you'll have to throw that switch to activate it, it won't automatically come on on its own. You can get another kind, that's an auto bilge pump, and it's got the switch built in, this float switch here. As the water rises, it lifts up this and that's what activates the fan to bring water in and pump it out.

If you wanted to make it an automatic one, you get a float switch as well, and you'd wire that in, and it would be the same thing that's built in the other one already, but it would just be an external panel that lifts when the water rises. But really what it comes down to is the gallons per hour. This one says 500. That's great. That doesn't really mean anything to me, because I can't see it, so we're going to put together a little test and compare how fast they get.Here's the plan.

We're going to pour 10 gallons into this container. I'm going to do that with every bilge pump to make sure we have the same amount of water and then we can time it and see how quick it takes to pump it out. First up is the 500 gallons per hour. This is going to be the slowest one we have, but the smallest one, so if you have a smaller boat and you don't maybe have the room to put the bigger 2000 gallon per hour one in there, this one's going to work for you just fine.Next up is the 750 gallons per hour. This one's going to be a little faster, but the unique thing on this one is this is an automatic bilge pump, so once it hits the water, it's going to activate, and once it gets all the way down, it's going to shut itself off.Now we're going to test out the 1,100 GPH bilge pump.

This one's a non-automatic, so it's switch based, but you're going to see quite a big difference from the last one. Now this one's going to be the same 1,100 GPH, but this one's going to be automatic. So again, you'll see it activate once it hits the water and then shut off Once it gets to the bottom.Now we're going to test out the 2000 GPH bilge pump. As I drop this one in there, it activates right away because it's automatic, and you're going to see it's going to take down the water pretty quick.Done. So that's pretty cool to see them right in a row and they actually do make a big difference, they don't just have the numbers on there for no reason. Our last one, our 500 was 50 seconds, and the highest one at 2000 was 22 seconds, so that's a big difference, and we saw that change with each one we used. One thing I will note though, is the sound sure didn't change too much. They sounded about the same, especially when it was submerged in water, of course it gets noisier when there's no water, you can hear it right before it shuts off, but most of these are going to be down tucked away, somewhere in your boat, so they're not going to be like right in front of the steering wheel and your face. You're barely going to hear it when it's going in your boat, pumping that water out.One of the biggest differences for me is the switch based ones versus the ones that have that auto switch. You can see again, as this water rises up, it'll lift this up and engage it. I think that's just a better way to go about it. I have to worry about flipping the switch or what if I forgot to do it and the back of my boat floods. Once it starts going up, it's going to pump that water out that way it never builds up on you.Whichever one you go with, it's going to get the job done. We saw that they just go a little bit faster. It's way better than using a manual pump or a bucket, I'd much rather have this do the work for me. I think that does it for our look at these bilge pumps. Hope that helps.
