$400 isn't cheap, but...

Just find that type of pump. You don't need all those sensors for sucking the residual water out of the bilge. Just rig a switch to it.

It's just a sea flo diaphragm pump, about $50.

Wonder where they got the pickup design from.. tempted to get this even though I have a home made one half way done.

Been thinking about installing a pump like this (no auto function though). I would hook it up to my swim light switch since it’s not being used and the connector is right at the transom. I think I would splice the discharge right into the bilge pump hose to go overboard.

I think it is a very cool system. Simple yet effective. I dont know that it's worth $400 so I wont be a customer, but if I were out of upgrades and looking for a project this could be on the list

Seems like a simple micro processor for the controller. Really don't need a controller like you said Aero...but does have me thinking about looking for a 3d printable design for the pickup... or just making one myself.. could 3d print a bunch for people here if someone has one.

I would use it for my oil changes too. Just hook up dedicated hoses for oil.

I have tried to use this pump and cylinder type pump on oil and gear lube no luck do work good on fuel and water.

reneechris14 · July 2020

Wanted a pump to do my outdrive lube I hate pump that little pump by hand for 20 minutes.

I’m in if you design a pick-up shoe!

This has me thinking..so I ordered a pump and came up with a pickup idea with stuff I have laying around.

The sponge Im thinking will suck up residual water to allow the pump to suck it dry. Going to try it out.

J3ff · July 2020

Genius. Let us know if that works!

skennelly · July 2020

Pump is supposed to arrive today. Might be able to bench test it tonight or tomorrow.

I have had a hose into my bilge for several years now and just use a brass npt end back in the little dip by drain plug. Never been any issues and works well. I don't get much water in bilge anymore but it works well after I clean the bilge to get that last bit out. I also have a built in filter, like what is in the fresh water line. You guys are over thinking this.😁

skennelly · July 2020

@Dream_Inn - what else is there to do? I like thinking.

Dream_Inn · July 2020

@skennelly I agree, always fun to think up some things! I'll be curious if that sponge starts to get a stanky smell. I guess adding fresh water in there once in a while may help.

@Dream_Inn - definitely a first prototype...LOL might now work at all. Sponge will probably fall a part over time too

Pat310 · July 2020

I like it. Maybe lose the sponge and just use a scotchbrite pad. Will get the pickup lower and will dry out better???

skennelly · July 2020

@Pat310 @J3ff

So I tried it out. In my prototype the sponge caused the pickup to create a ton of suction,. but so much suction that it hurt the water flow as the pickup was being sucked against the bottom of the bilge. I removed the sponge completely and the pump seemed to clear the water quickly leaving nothing behind.

I also want to play with the idea of a rigid tube mounted at the rear of the motor going into the lowest part of the bilge and see how that works.

That is exactly what I have and it was worked very well. I actually have it in the little dip at the drain plug. You may want some type of inline filter too.

Not bad for $29.95, should easily pump water.

You all are getting close to reinventing this https://www.homedepot.com/p/ECO-FLO-1-12-HP-Transfer-Pump-DC-with-Water-VAC-PUP61DC/207061358

Do you guys open your hatch every time you boat? I don’t want to be down there unless something is broken so the auto function is everything. Especially with leaky steering pin(s).

aero3113 · July 2020

I open the hatch at least once before the next trip to look things over, usually not on the day we leave.

rasbury · July 2020

I was looking for something like that @davidbrooks and ended up with a manual pump...look like that would be the way to go to get that last bit of water out...

davidbrooks · July 2020

I open the hatch about 80% of the time. Check fluids, look over everything and look at the bilge level. I keep a small shopvac on board to get what the sump cant. I like the idea you guys have but to be honest i feel it will keep getting clogged. Even though i am on a lift i will get water in the bilge all the time. Either comes from rain, wash downs or other.

YYZRC · July 2020

I also have a great DeWalt cordless shop vac that’s perfect for the bilge but still a PITA. I tend to check fluids upon return to the marina rather than before departing. Always in a rush to get going!

davidbrooks · July 2020

@YYZRC i always leave the house a few hours before everyone else so i can uncover, clean and check things out. Then sit and relax for a few before the family show up.

Wish I could see the inside of that pickup design, would be super easy to make one on tinkercad.com and print it out!

Howdy, Stranger!
