If your bilge pump has gone bad and you need to replace it, installing a new one should be as simple as disconnecting the old pump and connecting this new one in its place. If you need an extra pump in your boat, or if you are installing one for the first time, you may need to affix a bracket or steel plate to your boat so you have something to mount the bilge pump to.

SE27FR disconnected from strainer base

To mount this Seaflo pump, just pop off the strainer and attach it to your mounting point. Once mounted, the top of the pump simply snaps back into place on the strainer portion.

A thru-hull port (sold separately) will be needed for each bilge pump to drain water through. This will need to be installed in the hull, above the waterline and within 11' 2" of the pump. Keep in mind, the more water your pump has to push upwards (head), the lower your flow rate (or GPH), will be. If you measure from your bilge pump placement up to the height of your thru-hull, you can use the chart below to determine approximately how many gallons per hour you can expect this pump to move.

To route water up through the port, this pump requires 1-1/8" inner diameter tubing (not included) that secures to the outlet with a clamp.

Video Transcript for Seaflo Non-Automatic Bilge Pump Review

What's up everybody. It's AJ with Today we're going to check out this bilge pump from Seaflo. Now, this one operates at 2000 GPH, which is gallons per hour. I'm going to flip the switch and see how fast it gets this 10 gallons out of this tank. Ready Let's go.

Now, bilge pumps are used to get the water out of your boat. As you can see, it's doing a really good job here in this tank. That'd be good if you parked your boat out, and then raining, forgot to cover it up and it rained. You want to get rid of the excess water or, you accidentally go out without your plug put in the back of your boat and realize pretty quick, you need to drain that water out. It's a way quicker option than using a bucket or a manual bilge pump.

This is going to be a switch based bilge pump. And what that means is when you're wired in, it's going to have to have the switch to turn it on and turn off. It doesn't know when to turn it on and off on its own. So it's got that constant power. It's up to you to turn it on and off.

Now you can get an auto bilge pump, and that's what this is. I'm going to open it up and show you on the inside. It's got this float switch here. When the water floats up, it'll activate it automatically. You know, when it comes back down here, it stops automatically.

Now this one's not the same GPH. So if you still wanted the 2000 GPH, you'd get an external float switch, which you can wire in. And it's the same thing that's inside here. It's just going to be outside, next to your bilge pump. So it's the same thing. It's more like a paddle. So it'll float up to the top, activate it and come back down and shut it off. Let's take it apart and see what it looks like. I'm gonna take the filter off first. This is used just to collect any big debris like leaves or anything from getting in there and clogging up the fan and make sure that doesn't work. You know, then it can't pump any water. But with this on there, it's going to keep that from happening. Water comes in through here, comes right out the pump. To the outside of your boat. Couple of things to think about when you're going to get your bilge pump. Are you going to replace one, or add an additional pump to your boat If you're replacing one, then you're just gonna use the same hose you already had. I would suggest getting some heat shrink butt connectors, because you're gonna need them either way. You're adding one in addition to you'll still need to make those connections, make sure they're water tight and you'll need a hose because it doesn't come with the hose. It works with, bilge pump hoses of one inch and an eighth. So that's the diameter on the inside that it's going to work with. This is actually one of the faster bilge pumps we have. And it doesn't make sense to me just telling you, I'd rather show you. So we put them all to the test side by side and see how fast they go. Let's check it out. 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, 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. Stop. Now we're gonna test out the 1,100 GPH bilge pump. This one's a non-automatic, so it's switched based, but you're going to see quite a big difference from the last one. Done. 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. Done. 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 lowest 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. Even here, right before it shuts off. But most of these are gonna be down tucked away, somewhere in your boat. So they're not going to be like, right in front of the steering wheel, in 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 base ones verses the ones that have that auto switch. You can see again, as this water raises up, it'll lift this up and engage it. I think that's just a better way to go about it and not 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 this does it for our look at these bilge pumps. Hope that helps..
