Title: Auto Bilge Pump
Post by: Painlesstom on May 17, 2012, 01:01:44 PM
We've all seen the extra boss castings in the jet pump housing and while some know what they are for, others don't. I'm not sure if anyone else has done this before, I know a couple that have talked about it, but I finally drilled and tapped the siphon boss for a fitting and went out to see how bad it sucked. Well it sucked a gallon a minute, and for such a simple modification, it's going to be a huge solution to those who need a way to rid their hull of stray water that didn't know how to stay where it came from.

The video shows a full bucket of water being sucked dry by the jet pump siphon, this was done at half throttle at approx 3000rpm. I had pumped a few bucket fulls empty while at full throttle and it emptied much faster. Of course with a clutch there would be no pumping at idle but since the siphon is working every time the pump is working there wouldn't be much time for water to accumulate anyhow.

I'll post more once I've installed a bulkhead, quick disconnect, and figured out a pickup location for inside.

Interesting info on the suction of water via the pump, will definitely consider it.  Have had electrical bilges cause lots of headaches, and most of the time when i most need them to work.  Look forward to seeing it in place and working.

I'm pretty excited to get it finished up and get some more testing done.

I used the same type of quick disconnect that I put on my fuel and pulse lines. I used the male side for the hull, drilled a hole in the hull for the barbed end to pass through with some silicone and used a large stainless washer on the back, with more silicone, and pushed the vinyl tubing on to hold it all in place to cure. I've got a pickup grate coming that I will tie the pickup hose into so nothing larger than the hose can handle would get sucked up. Going on vacation next week so that will have to be dealt with when I return. Pictures say the rest for now.  :)

Awesome Tom!!!  Another one of your fantastic ideas and this pump requires no battery to work just take your boat for a ride and she'll keep on sucking :)

Good grief, where do you come up with this stuff, Tom ?!  An awesome idea..., I wonder if that is what the original intent was.    It is time for you to come up with a Painless Boat !

Tell you what, when you come up with a Painless Muffler to quiet the lawnmower-like drone of the current Suby engine - I will buy a clutch for each of my Mokai's !!  Deal ?!
Title: Re: Auto Bilge Pump
Post by: Hillbilly on May 23, 2012, 08:07:18 AM
It is a great idea, Tom.  On/off, if needed could be handled with a fuel shutoff stopcock through the upper right side of hull. Just reach back from the seat to turn it. This also opens the possibility of "out the back" exhaust routing for those who were worried about getting water in the boat.  "Out the back" directs sound, heat and exhaust where they belong and makes the boat quieter to drive.  The stock Mokai muffler is a beautiful unit and would be easy to run out the back with a simple bolt on header. With proper bracing, that may be an inexpensive solution for many.  The muffler brace boss is already on the muffler.
Title: Re: Auto Bilge Pump
Post by: Painlesstom on May 29, 2012, 04:10:16 PM
Yup, full time on is the easiest way to set it up. Just loop the inside line above the water line so water won't flow back into the hull when the pump isn't turning. Then there is nothing to malfunction and no valves to mess with. Just twist the throttle and it's pumping.

I got my pickup grate in and will be posting pictures of how I finish the inside along with the parts links. Playing catch up from being on vacation last week but I hope to have something done by the end of this week.  ;D

Make sure to loop the pickup tubing (1/4 clear vinyl from hardware store)  in the hull so it is always higher than the water line, or water will flow back into the hull when the pump isn't turning.

Does it pick up & pump out sand too?   Because I'm always getting in & out with wet boots, I drag sand/dirt inside, and the water seems to run to the back, along with the sand & dirt.  I think in my boat, the inside of the grate would eventually get filled with sand & small gravel if it doesn't.   But another great idea!

If it will fit in the hose it will get sucked out, the grate could clog I'm sure if enough stuff gets in it. A strainer could be made from a screen cone that would prevent a full on clog and still let water get pumped out, sand too.

Hittin' the river tomorrow to give it a test, hope to have some video to share when I return.  >:D

Post by: Painlesstom on May 31, 2012, 02:01:45 PM
Made it out to the river, then left the video cam in the truck. Seems through the connector and the loop there is enough restriction to slow the flow, it did pump some water out but not fast enough to be useful. Going to look into some free flowing check valves and see what I can come up with so there is a direct route from the pickup to the pump without all the twists and turns. I'll get this figured out yet... lol
Title: Re: Auto Bilge Pump
Post by: Hillbilly on June 03, 2012, 12:36:14 PM
Tom,

I'm starting to install mine.  Your video test shows very good flow through a longer 1/4" tube than we will need in the boat, even with the loop.  I see two possible restrictions.  One is the quick release connector.  The inside diameter of mine is 3/32" - pretty small.  The other possibility in your setup is the 1/4" tubing sliding deep into your pickup foot and sealing or restricting against the hull floor.  I'm placing  a brass nipple fitting on my pickup foot - held at a set height by a nut and washers. 

I really think the restriction is in the connector. 

We can check this by running our 1/4" tubing up over the transom and down to the foot. I may use 5/16" fuel hose. The thin wall plastic tubing may heat up in the engine bay, get soft, and collapse under suction on a multi hour run.  It will be a few days until I get out.
Title: Re: Auto Bilge Pump
Post by: Painlesstom on June 03, 2012, 06:09:46 PM
Decided to gut the quick disconnect of it's shut off valves so it's a free flowing piece with no restrictions, and sure enough that was my problem, the shut off valving was too restrictive. Everything set up exactly like my previous pictures show, with the modified valve, sucks the water right out of the hull. It works great, the loop above the water line keeps water from flowing back in when idling so even if you forgot to hook up the pump connector your hull wouldn't flood as a result. If you somehow managed to take on a couple gallons of water instantly, it would take some time for it to catch up but it will get the job done. I think it would keep up with the average amount of water that could typically be splashed in without problem. I plan on changing to a larger screen type strainer pickup as opposed to the black plastic deal from the pictures. The tubing should be as close to the hull without being able to develop a clog or restriction, mine is about 1/8th inch from the bottom right now and once the connector was opened up it worked great, I just think a screen strainer would allow it to work faster with less chance of clogging up.

Gutting the quick disconnect was as simple as using a long locating dowel punch to tap from the barbed end out, breaking the valve free and letting it fall out with it's spring. Just be careful not to damage the female side where the o-ring seats!

I dumped in a little over a half gallon, so you have some point of reference on how fast it's working.

Tom

We are thinking along the same lines but as usual, you are way ahead.  When about to install the pickup foot, yesterday, I had an idea that will "get it as far back as possible" and also be removable to unclog as necessary.  Made from 3/8" fuel hose scrap and a few pieces from a parts drawer.  It is 6" long and fits at the very rear, with 1/2" inlet centered behind pump.  If you think it's clogged, just pull it out and check, clean it and slide it back in.  Could screen the pickup end, too.

I noticed the fittings can be bought in valved and non-valved, suppose the non-valved would do the trick?  Will have to wait till next week to get started on installing the latest Painless Mokai improvement.  Really appreciate Tom and Hillbillies posts and work on this bilge project.  Water has been a serious issue at times for me, requiring a quick stop for hull draining.  Since the boat is sensitive to a few gallons of water resulting in performance issues I consider this one of the most important safety developments for the boat.  Clutches, pump improvements, alum wear rings, and now this improvement? What next, maybe a Turbo Charger?  Big thanks for the bilge posts.  By the way if anyone is interested in big improvements to their Mokai operation, get a Painless clutch and Painless Alum wear ring TODAY! 100% Quality, 200% Functional  :)

If you can find non-valved quick disconnects then that would make things that much easier for everyone.
Going out today for some more testing with a new screen type pickup strainer, will post pics and details when I return.  >:D

I stopped at Lowes on the way home from errands.  Plastic tubing is very reasonable.  $10 will do about 7 boats.  Also got some brass fittings.  Here is my hose pickup arrangement.  All clear so you can see if clogged.  There is a 6" piece of 1/2" id tubing for the pickup with a piece of barbed brass at the far end to weight it and keep the end open.  This tucks snugly at the very back of the boat behind the pump.  Pull it out to check it.  You can screen the end if needed.  Lightweight and cheap.

Testing with the screen was even better and how I'm going to leave mine. That pickup hose you made, Hillbilly, sounds like a good idea for being able to reach even further back but I think you would still need to put some type of screen on the end.

The final drill bit size I used to open the port on the pump with was .270. That larger size increased the amount of suction quite a bit and sped the pumping process up.

LessRon, Excellent find on those connectors!! Two thumbs up for that one man, that is going to make life much simpler for many people.
I went through the available options and bookmarked the links for the ones that would work best for this bilge setup.


This hooks to the hose coming from the pump- http://www.colder.com/Tabid/72/MaterialID/1/cID/1/sID/6/tID/1/pID/132/Products.aspx

Any more updates on this. I have the sea doo suction pick up block i bought off ebay and the fitting in my tool box and forgot all about it until i saw this thread.
Title: Re: Auto Bilge Pump
Post by: Painlesstom on July 29, 2012, 09:26:10 PM
Nothing more to update really, everything is just like I described in my last post and it's been working great. I'm not sure what you have from a sea doo, but I doubt you'll need it.  The fitting needs to be 1/8 npt to 1/4 barb, you will need to use a die to cut the threads on the fitting so there is no taper. Drill the pump port straight or you will end up pumping water in instead of sucking it out. My previous posts detail the connectors and drill size etc..

For anyone doing this themselves...

The casting inside the pump is angled so the leading edge protrudes further than the trailing edge, that ensures that the water flow hits that leading edge first and gets deflected over the trailing edge which is what creates the vacuum. If the hole is drilled so it exits just forward of that leading edge, and removes it, the water flow wouldn’t go over it and would instead hit the trailing edge first and travel back up the port and into the hull. It’s the same principle of blowing across a straw and getting your drink to travel up it, if you change your angle too much you end up blowing bubbles in your drink instead.

Tom,

What is your best estimate of gpm with the latest bilge?  In chop, taking water into cockpit or while anchored to stern going into new muffler cover opening.  Standing water up  to top of engine hold down plate that could be safety issue and does impact performance.  Long runs do not appear to drain off.  Can find no apparent blockage.  Any ideas on how to check bilge further or should a skirt be retroffited block  below muffler opening?  Any feedback appreciated, John
Title: Re: Auto Bilge Pump

Is there a brass tube on the inside of your bilge port on the pump? It should pump approx 1 gpm at full throttle.

Reach in from the nozzle, and see if the tube feels loose. Unscrew the fitting, pop the tube out and use silicone to glue it back in the hole, then reinstall the fitting making sure no silicone is in the passage. Let cure. Should solve your problem.

During my last long trip, I noticed that the bilge pump wasn't working effectively.  High waves and muddy water put a lot of muck in the boat.  I cleaned my strainer and it helped a little, but not great.  Today I was looking in the boat and noticed the plastic tube between the strainer and pump was nearly filled with sand and dirt down low where it made the turn upward from the strainer.  Took the tube off and blew it clean.  I'll bet that was the problem.  The bilge pump is such a great addition to these boats.  If yours stops working, check the tube.

Thanks for the insight. Another way of clearing that without the need to take anything apart is to use a garden hose to shoot water through the line from the hull connector.  \./8

The comment on flushing with garden hose makes good sense.  I moved my strainer more forward to more easily pull tube end up and out of engine compartment during this maintenance flushing.

I have noticed that a debris plug typically develops at the quick disconnect adapter fitting. There are plastic flukes on the inside of this adapter that do narrow the clear passsage.  Anyone drill these out for they do not appear to impact quick disconnect feature?
Title: Re: Auto Bilge Pump
Post by: Hillbilly on April 25, 2014, 09:49:54 AM
Tom's auto bilge pump is one of his best improvements IMHO.

While cleaning boats for the new season, I was reminded of the fine mud lining the vinyl tubing that collected over last season's fishing and travels.  At one time, one auto bilge stopped working because of fine mud in line.  I just replaced all my vinyl tubing.  Three boats, four dollars, ten minutes.  Will work like new again.

Also saw some polyethylene tubing at the hardware store.  It is semi-opaque and stiffer than the vinyl.  Anyone think it would work better than the vinyl?  It does cost a penny a foot more.
Title: Re: Auto Bilge Pump
Post by: Painlesstom on April 25, 2014, 12:51:14 PM
Thanks, George. I would think that flushing the line would be all that was needed, was there so much build up that it clogged it shut? If you wanted a tubing that would perform better, then silicone would the ticket. It's much softer, and could be worked with your fingers to break up any build up while flushing. The only reason I didn't use it for these kits, is it's $2 per ft price. That is what you would find on any jet ski that has a venturi style bilge. I haven't had to touch either of my boats though, tubing is stained with mud, but always carries the water out fine. Right where the tubing goes into the strainer, I purposely set it up so the hole narrows in an effort to prevent anything being able to lodge itself past that point.
Title: Re: Auto Bilge Pump
Post by: Hillbilly on April 25, 2014, 01:46:27 PM
It actually was clogged with fine mud.  Cleared it out with water during the trip and was OK.  Lots stuck to the inside of the tubing so I just changed it.

Post by: bizler on August 08, 2014, 09:00:57 PM
After I installed my auto bilge pump, I noticed that I was collecting water, perhaps a cup full or so, at the end of a cruise that I had not had before.  I usually had only the amount that I carried in on my boots. It occurred to me that maybe at low speeds, the outlet might become an inlet for a short time.  The auto bilge would then draw out most of the water but some would always remain.  So, after some thought, and looking for a commercially-made one-way valve, unsuccessfully, I decided to build one myself.

I took a section of 5/8" dia.  nylon 1 3/4" long and drilled a 3/8" hole through it and tapped both ends with 1/8" pipe threads.  I purchased two brass 1/8" X 1/4" barb fittings.  In one of them inserted a 7/8" section of 1/4" tubing and soldered it in.  Then I used my mill to cut three 1/4" flats on the tubing, creating three windows through which the water enters.  I had to scrounge a bit to find a floating bead the is about 5/16" in diameter and relatively round and smooth.  I had some fishing beads called "corkies" that were pretty close.  I filled the through hole in the bead with Gorilla Glue and made it as round as I could with a little sanding.

Then I assembled the two fittings with the bead in the nylon tube, and walla,,,  A one-way valve was created.

I cut the vinyl tubing between the panel mount fitting and the high point in the line and installed the valve.

I ran Mokai about 25 miles today at various speeds for about 4 1/2 hours.  When I got home, I wiped up the residual water with one paper towel.  I like the valve...
Title: Re: Auto Bilge Pump
Post by: Painlesstom on August 08, 2014, 09:42:45 PM
Nice, Bill. I'm surprised it worked. I initially tried a check valve before I realized it wasn't needed, but there wasn't enough suction to overcome the valve... So nothing got pumped out.  The tubing being looped up keeps water from coming in when the pump isn't running, the only time that could be overcome is if you parked the stern facing a current so water was flowing into the pump from the rear. Then some water could be pushed up the tube and into the boat. But it would take some unusual circumstances, and a substantial current, to see that happen. Your valve looks nice and neat, I'm glad it worked out for you. Good Job!  \./8
Title: Re: Auto Bilge Pump
Post by: bizler on August 08, 2014, 10:55:53 PM
It just occurred to me, perhaps it is my reverse mechanism creating a little bit of back pressure at the nozzle that is the reason that my Mokai is picking up some water when others don't.
Title: Re: Auto Bilge Pump
Post by: Painlesstom on August 08, 2014, 11:39:57 PM
That could very well be the case, you would be creating a pressurized area inside the pump. I hadn't considered that, good thinking.

Post by: Hillbilly on August 09, 2014, 08:28:57 AM
Earlier this spring a buddy was using one of my boats and a lot of water got in.  He was fishing in fast current with nozzle into current.  Got enough water to stall the boat (water covered wires). I thought my tube had dislodged but no.  No problem since then.  Bill, your valve is a beauty.

After reading up on this whole discussion, I am left with this set of questions:

I take it that if the pump pick-up is only sucking air, it will not affect the pump performance?
The most recent URL's are not returning any results for the quick connect fittings from Colder Products. :(

Since these URL's tend to age (become useless) it would be very useful to just specify the company, type of fitting (valved or non valved), size, material etc. so one can just go to the related website and find the part based on that info?
Finally, since this topic has aged, is it still considered a useful thing to have in the boat?
Thanks for your feedback.

It has zero affect on pump performance, it's on the outlet side and is using the flow to generate a venturi effect. I haven't recommended it for the Es-Kape due to the hull connections being so exposed on the new hull, easy to break them, and it would only evacuate water from the engine compartment since the cockpit is now separate. The Es-Kape has power, many of the old boats did not, so the option to have electric bilge pumps is there. One for each section and you don't have anything to worry about.

I see this is kind of an old thread, but I couldn't find a more recent on topic. Soooo... hooked up my venturi pump bilge pump like the pictures, and it pumps water back into the boat with pretty good force. I can't see that I did anything different than the instructions. Any thoughts?

Some pictures would help. Did you drill the pump and install the system, or did you have me do it. I don't recall doing one for you so wanted to ask.

Sorry....just realized I never responded back to you Tom. I did it myself and got it worked out but don't remember exactly what I did to make it work.
