Windscreen washers

I intend to instal screen-washers above my lower helm windscreens because dried salt-spray makes for poor visibility; especially when heading into the sun - and there's lots of that here.

Fresh water from the boat's pressure system would feed a small header and "jets" made of 1/8" brass tubing located above the windscreens. I have not yet worked out how to turn the flow of water on and off. A*valve by the helm, a push button triggering a solenoid valve??

Do you have screen-washers on your boat and if so how do they work. I don't want to reinvent the wheel, so suggestions please.

* Go to a junk yard or ebay and find a used auto unit, plumb it, wire it and you are good to go.

RE: Windscreen washers

Shoalwaters,

I have a link you might want to try. At $20.00 for the full kit it sounds like a bargain.

Shoalwaters,

Here is a picture of how Mainship does it.* The blue line is a cold water line off of the pressurized fresh water system.* The solenoid is operated by a switch on the lower helm.* The black tubing is connected to three simple tubes that are directed at the windshields.* Simple and works flawlessly.* If you want the solenoid part number I may be able to dig it up for you.

RE: Windscreen washers

JT and Rob, thanks for the input, but ,as stated, I want to use the boat's pressure water system. That gives me a 200 gallon screenwash reservoir!

JD, That little solenoid valve looks like it would do the trick. Manufacturer and part number if you can find them please.

Mike

Mike,

I have sent an email to the parts guy at Mainship and it will take him a day or two to return the answer but he will send it to me and I will get it to you.

*I believe that part is a Hotpoint ice maker water control valve.. I just worked on our icerette ice maker last weekend and I recognize the valve... about $ 18.00. They may be only AC but who cares.. the inverter will take care of it.

You should be able to find one at 12 volts easy enough. I'm sure the identical valve is made in 12 volts.

Windscreen washers

I think I saw a photo of Carquinez Coot's(?) windscreen with screenwash hoses attached to the wiper-arms. That sounds like it could work for me too. Can't find the pic now though. Anyone?

Here is the manual washer valve on our boat ( red arrow )* No electric and very simple.

Silly me.* I searched for an hour fruitlessly*looking for the windscreen fluid container.* Finally dug up the boat's schematics and found the water is taken directly from the pressurizd fresh water system.

JD, did Mainship do that sloppy*wiring too?

*Here it is.* The hoses run down the three wiper arms to a nozel.* One shown here.

RE: Windscreen washers

My*washer control is*in the subpanel in the lower-left part of the panel.* The third to the right switch on the lowest row controls the washer, and the three switches in the middle control the three wipers.

******** I have them and they are fed from the fresh water tank. When you push the rocker switch for windshield wash, all three fire at once. You let them drain down the windshield(s) and then you turn the wipers on. Works great and they are 12V. No hoses on the wipers are needed.

*

The water fittings are just to the right of the wiper actuator and are centered on each windshield. (3).

*The Mainship I have has them fed by one solenoid that is activated by pushing the*number one wiper switch past center once it is "on" and holding it there, it returns to the normal "on" position when released.* So the wiper in front of the helm has to be on but*the other two do not.* And yes they are fed from the freshwater tank so you must have that system up and running.* Mainship used the same system as Seahorses Halverson.* Three nozzles up at the top of the wiper arm.

Windscreen washers

I used Spraying Systems nozzles of about .8 gpm in a 45 degree fan mist, one over each of 5 windows in the pilot house. A simple solenoid valve from Grainger with a console mounted swith completed the equipment. I apply Rainex to the windows, so that when I mist the windows, the fresh water clears off salt quickly providing excellent visibility. I would not bother with wipers based on my experience with this system.
