Hi all,

I'm looking for a pump setup that could be deployed astern or installed in the interior motor area with a spigot to an overboard pipe/hose that would then pump the water to two spigots imbedded in the motor well side wall and the anchor locker via hose and a y valve in the interior. The concept would be to activate the pump and pressurize the system to a quick connect hose in the anchor locker for anchor washdown or the same hose quick connected for a cockpit washdown/raw water shower in the stern cockpit area without using a thru hull setup.

The challenge is to find a pump that can lift the water from astern (without a thru hull setup) up the 4-5 vertical feet to the cockpit user level and then direct it 25 feet forward and up another 3-5 feet to the user level at the anchor...all while self priming?

I searched the mods and found no one with this setup that could be very handy to us all...guru's attack the problem!

Thanks for your help in advance...pumps are tricky as I tried to figure out a live well setup under the 26m captain's seat and most off the shelf pumps will not self-prime and lift the water up from water level to cockpit level.

I look forward to your engineering and research prowess benefiting the group!

I did this mod on my years ago.

While it's not exactly what you're looking for, you may be able to branch off your own use. While I no longer use this system, I've left the system up to use as raw water wash down that I need to finish - but the bones are there. Namely: wired in pump with filtered intake hose plumbed through motor fittings. It now has a 4 foot hose leading out the back of the boat 12"s above water line. Add a strainer to the end & drop into water for endless supply. The pump out connected to a garden hose Y valve with shutoffs that fed (1) a 50' spiral hose & sprayer on transom I could use anywhere on deck for wash down. & (2) a 1/4" line feeding 2nd galley faucet with shutoff.

You have to flush this system with fresh water every now & then.

Hope this helps prime your mod pump

I installed a washdown pump. I use a thru hull under the aft table seat and have the hose fitting in the motor area. The plastic coil hose that comes with the pump is junk.. I have recently bought a collapsible hose that packs up like a piece of dock line.
Yup - let the anti thru hole mafia proceed to flog me

Gazmn,

Thank you for the link to the mod...not sure why I couldn't find it in my searches (head space timing of the operator?)?

So to clarify...because I used two different Johnson pumps for the failed live well mod (4' lift)...you put your strainer off the stern at water level (on a 3-4'hose)...and this Johnson pump lifts the water...self-primed...up to cockpit level for a shower...and can push it forward the 26' and up again to above deck level (10' above water line and after a 26' run)...at user-hand level to wash off an anchor...with decent pressure?

I'm not questioning you or trying to put you on the spot...this has been a 2x pump ($250) challenge already for me and if you've got the magic bullet...I need the model number!

Thanks for your input and help...this has been a frustrating one with little assistance from the WM pump salesmen!

Respectfully,

David

Thanks RobertB!

I'm really trying not to do a thru hull to keep it simple down the road. I did think about a y valve off the cockpit drain to a pump combined with a 90 degree below waterline pvc insert into the exterior of this drain fitting to increase pressure/decrease draw...that might still work...with the right pump (2x attempts...no success thus far)?

Any ideas?

Thanks,

David

I too do not want holes in the bottom of my boat.

Buy a washdown pump. It has plenty of pressure for what you want.



I mounted mine to a piece of wood glued to the inside of the hull behind the aft berth. Plenty of space back there for it below decks. Wire it to a fuse and switch.
I bought a good quality garden hose. Drill 2 x 1 1/4" holes from the motor well (see below). Feed garden hose through the holes to the pump inside. Preserve the male fitting on the pressure side. This becomes your hose attachment point.
You will need a male and female hose repair fitting and hose clamps. Cut a piece of hose to the IN side of the pump and use the female fitting. This becomes the raw water in.

The white coiled hose meets with the male fitting from the pressure side of the pump. This is a cheap garden coil hose. I have a 50' one that reaches easily to the foredeck.
The black hose is the intake. You don't need the male/female fittings, but I want to be able to take this completely off if I want.


So we have a coiled up hose in the motor well. I have a metal hanger to hold it. Be creative..or more creative than I was.
A 3' hose for intake. I also attached an RV water filter to filter out smutz from the raw water. The kit comes with a strainer, but this filters more.

To deploy this thing, toss the intake hose over the back. Here you can see it sinks with the filter on the end. Turn on the pump and you have a garden hose that reaches the whole boat with plenty of pressure.


My marina has no dock water, so this is it. We have a "mist" on the dial of the hose nozzle. We can mist ourselves on hot days or hose kids swimming off the back. When done, pull up the intake, coil the hose. I leave the black intake hose coiled in the motor well.

Russ,

Awesome!! Thank you and the other contributors!

What I like about your setup is a lot less hose laying/fitting to the front of the boat and a more gradual lift thru the 50' hose (maybe I could get a 35' for increased pressure?)! Plus it's all interior/salt protected (do you know if they have brass/plastic fittings for your setup?). Do you have a lift rate (height) and gpm for the pump you used?

We have a lot of muck in our waterways so an anchor washdown would be great...we also have some great water to shower in near the inlets...so this would work great!

Thanks again for this and any other ideas the group generates!

No prob Bro

I'll explain what I have currently & how the old mod can still be relevant. You're limited to 3 pics in mod section so I was limited that way. But hopefully my babble was clear.

That system was primed by the fresh water supply. With a turn off of the freshwater & a turn on of the salt water @ the inlet Y. It had enough suction to suck ~ 6' salt water intake hose.

I've since separated my fresh water from salt water. 2 separate systems but haven't used the salt in a bit.
Fresh Water:
Plastimo 31 Gal under front V berth. Careful with these, they tend to leak Fill hose is detailed in mod. Plumbed to: filter, pvc shutoff & hose connection to pump inlet. All housed in front section. Y outlet connection: (1) to 3/4" garden hose runs along port side bilge aft to through hull to transom & connects to 25' fresh water transom hose/ shower. (2) 3/8"? hose to galley sink faucet. Also run aft on port side. I also had a tee run from there to head faucet but shut that down, too many leaks So no water currently to head - which is just opposite the galley in the anyway. I can take three steps to wash my hands.

Salt water:

Starboard side aft in pizza bunk, see mod. As already stated,[now minus Y valve] ran ~1/2" hose through same hole as motor cables, so it's low on transom, maybe 12" above waterline, inline filter, hose with strainer to drop in water. You could figure way to back fill or prime - but it worked for me.

The outlet was plumbed to through hole low on starboard side of transom to 50' salt water hose.

Salt water starboard side:


This pic shows both sides & through hull heights for garden hoses


Ditto all that Russ said. I use the same pumps & premise.

I think this is the pump I used.
http://www.jamestowndistributors.com/us ... n+Pump+Kit

It's only lifting a foot above the water line because the pump is essentially at the water line and self primes fine as long fittings are tight.

The pump is all plastic fittings. Hose is garden center hose. Buy a good quality hose with brass fittings. I think it's 3/4 inside diameter.

The pump has plenty of pressure. It's almost as powerful as your house spigot. It will blast 30'. Use heavy guage wiring so the pump doesn't starve for juice.

I drag my anchor through the water to wash mud off. It is nice to spray the deck and people down. My dinghy seems to fill with dirt. I can hose it down.

I done the wash down /cockpit shower mod @ the transom here is the transom water pick-up fitting

I have one more pic with the water p/u filter inlet line I,ll post later when I can find it or take a new pic
hope this helps u out a bit

Thank you all!!!

This is very helpful and I'm embracing the simplicity!

So...a concept to proof thru all your experience:

If I take this 5.3 gpm pump you all use...mount it in the port stern interior wall of the motor well ( down as low as possible)(heavy guage wiring)...drill an exterior outlet, quick disconnect, hose spigot in the motor well area connected to the outlet on pump with a short hose section...drill a second intake hole low in the motor well wall with a 90 degree pvc elbow with a soft tubing grip...attach a flexible hose to that with a strainer on the end that will reach 6" below waterline (stored when not in use in the cockpit drain/sump area) ...wire the pump to a fused switch on the main fuse panel (might need one with more switches?) OR to the helm pedestal on a waterproof, fused switch for convenience.

And if I switch on the pump it will not burn up while not using the hose (walking to front/closing the spray), but the pump will automatically cut on/off as water is demanded correct?

Please be critical or skeptical if you don't think the above will work.

I like it because it's all hidden away in the interior aft section...no new exterior holes above or below waterline...uses water pressure of submerged intake to help prime the pump...and I could put a quick connect on my under helm seat livewell and attach the hose there when fishing to stir the bait water!

Thanks again for your experience/thoughts!

I located water pickup (a thru hull) midships based on recommendations from the dealer - a place that was always going to be underwater. I really am trying to get away from rigging the boat every time I want to do something. Having to get the hose out and open the valve on top of the thru hull is enough. I have my pump mounted on the low bulkhead near the battery box - short wiring and good access - and dry. The pump I use has a pressure cutoff so it will not pump when the valve is closed. I rigged this for both washdown and to experiment with a livewell setup.
The thru hull will probably do double duty in the future if I install a proper air conditioning.
I have one of the WM Jabsco kits - the coil hose is junk. The pump is on a dedicated breaker.

RobertB,

Thanks for the info!

I'm not against thru hulls...I've got a lot of experience on bigger boats with them...but for simplicity/ease/timeliness of doing this project, I'm trying to stay away from that route for now.

I would be curious to discuss your a/c project sometime too! I decided to go with a window unit, two-part hatch cutout to walk around when it's in place in the companionway, and a Honda 2k in the dinghy (I will only use it for summer Keys or Bahamas trips). But if you are installing a thru hull...I'm guessing you figured out a way to put a real unit down below? If so, I'd love to know the specs for btu's and power?

Thanks again for your input!

David

I am experimenting with a dual hose standalone unit for now. I have it tied down behind the galley and made a louvered setup that installs on one side of the companionway for the hoses. Also made a second set of hatch boards to fit. Just no way on an we were going to get in and out with an AC mounted in the hatch and I was not going to lug one out on deck to put over the forward hatch.

I would install a water cooled system in the front storage area. Challenge is arranging the air supply and returns.
