Always had water in the bilge between the engines on the 310 so I decided to take a shot at a DIY project I seen online. I plan on plumbing it to the shower sump.

I’ll install it over the Thanksgiving weekend and report the results.

All items purchased from Amazon.
Only have the timer setup for now. You can program it for 1 day or all 7 days or anything in between, 20 times a day on/off. I have it set for 3 days for 8 minutes a day. The timer was $10 bucks and I think a quality and reliable water switch could be $50 bucks so I went with the timer 1st and I can always add the water switch later.
This is was good information for me

Nice setup, probably better then this one: https://www.seaflo.us/product/dry-bilge-system/#undefined

Same sponge concept, they seem to work the best. I have been considering making one for a while, I just want one that senses water and gets rid of it. But the timer thing works I guess and you can connect it to the existing bilge pump constant 12v for an easy install. Great post, post back your experience with it.

I would absolutely do this if I had somewhere to run the discharge hose.

i had the exact same timer on my 10 meter.

It's a 12 volt timer used primarily in the birding industry (chicken coops) that can easily run a bilge or other pump.

I had mine set to run twice a day for :30

worked perfectly for several years !

The idea of running the dry system to the sump is great !

BEST !

I bought a pump planning to make one, but we just finished our basement, and you can guess how many boat projects got worked on lately.

But for $140 for an off the shelf unit, I think I might just buy it. I would have to read up on it, see if its just timer activated, or if a water witch could activate it. Regardless, that might knock one more item off the list.

But to @Lenny3, nice work!!

If your referencing the one from the link I posted, it is the same thing, timer activated. I am also wanting a water activated system.

Really a sweet setup. I like the diaphragm pump as it doesn't require water to cover the inlet/sponge to remove every drop like a centrifugal bilge pump does. It'll pump air just as effectively as water.

I was able to temporarily install the dry bilge system on the boat this past Saturday. The hardest part was installing the the pick up to the bottom of the bilge. Since I was in test mode I didn’t want to run screws through the fiberglass just yet so I used plastic zip ties. I did find that the discharge hose would be best to run to the engine hatch drain system.

This set up works extremely well. The 1/8 intake hose makes things slow going but does suck out most of the water.

I did find out that the Surflo pump IS ignition protected but the timer is not. If you are considering a system like this I would mount the pump in the engine bay and mount the timer near the helm. The plastic box does make it look fancy but not really needed.

Lastly, as Lazy Daze suggested, “find the reason you are getting water in the bilge”. In my case I found that the starboard shaft seal is indeed leaking. I have a haul out schedule in the beginning of February and will add this to my list.

So Bill the owner called me today to tell me that while he could full fill my order but he had a new version coming out next month with updated software. Also they are going to do a 4 pump system. I told him to hold my order and call me when he is ready with the latest version. Super good guy… Looking forward to getting mine sometime in mid to late January.

Whelp....my first impressions are not great. But I have high hopes that it works well in the long run.

My unit arrived wet inside the packaging. I hope this indicates it's been bench tested? It's also all scratched to heck all over, pretty beat up. Since this is not a cosmetic piece I'm going to plug her in and give it a go this weekend (on my bench) to see how it works. If this were something I cared about aesthetically, for $200, I'd be sending it back.

An interesting design decision - the big label they apply to the pump is not waterproof. Mine is starting to peel off due to the wet shipping situation :)

These photos are straight outta the box. This is a veteran owned company so I'm 100% going to do my best to love this thing.

Bummer, that look used to me, not bench tested. Also, the piece in the bottom right of your pic looks bent or broken. I would send that pic to them and see what they have to say before you go any further.

I have a little water that collects in the stern bilge, and then some that collects in the sump under the aft seating area in the Salon. I was going to try and hook everything to one of these, but I've decided to split it up between two pumps. One in the engine room and one in the salon. I bought a Sea Flo dry bilge system for the salon, and am going to wait the upgraded version of this thing (assuming Stee6043 gives it his stamp of approval) early next year. Will let everyone know how the sea flo one works. It looks more professionally packaged, I can tell you that.

Well in spite of it's looks (as shipped) the performance of this unit seemed to be pretty great on the bench. I was curious if it would pump with enough pressure/volume to get all of the water out of the lines once the water cleared, and it did.

It pumped about 1/4 gallon of water in maybe 30 seconds, max. It's no bilge pump but it'll certainly clear the leftovers in the 2 minutes it runs. Allegedly it'll run for 2 minutes every 12 hours but I am not going to leave it plugged in overnight on my bench, I trust the technology :)

I located the pump 30" or so above the buckets and then a catch can another 12" or so above the pump. No issues with a little bit of head, I believe she'll work like a charm...and it's quiet! Can barely hear it running.

I have this unit and it works but mine has two inputs/pucks and is very quiet. However, it does not turn on by itself. I have to click a remote control for it to turn on.
