Is it possible to do this? Can it be done thru hull in order to pick up the water while cruising. If not a thru hull what can I do to have raw h20 circulation to my above deck livewell tank?

My Conquest has such an installation. The through hull is on the hull bottom about 2-3 feet in front of the transom and midway between the keel and chine. There is a strainer/scoop over the through-hull hole.

Can anyone help me out on this. I am having the boat re-wired and want to know if there is a way to do this. I am also wondering if I can get 2 batteries inside my is not the super-console.

I ordered my 1989 25 Outrage with the factory installed Raw Water Washdown. Here are the installation details, which I "assume" would be the same for a 22. Since this was a factory only option (about $500), I also assume BW didn't want the Dealers installing this at a later date, which may indicate it's degree of difficulty.

To me, the raw water intake & scoop/strainer, on the starboard side of the hull, directly under the very stern edge of the big bow deep well, is the difficult part of the installation. It is a bronze combination strainer/thru hull, about 2" x 4" on the outside of the hull, with 3/4" threaded long thru-hull. It enters the inside hull in the starboard, aft corner of this bow deep well. From there, the intake tubing goes straight up into the under side of the console, coming through a hole in the gas tank floor cover and the console floor. The Shurflow pump is mounted on the console floor (in front of where the cabling comes into the console), and is wired to a push-pull switch on the switch panels, lower front of console. Power to the pump is fused off of one of the accessory fuse boards on the inside of the console. From the pump, the 3/4" pressurized water tubing goes back down into the wiring tunnels, and comes back up at a male Perko supply fitting (for a hose connection) on the aft surface of the plastic Starboard side cover. The washdown hose can be hung coiled under the starboard gunwale, adjacent to the pilot seat.

My hunch is that the thru-hull fitting was installed before the boat's gas tank and floor covers. It is not an easy place to access from inside the boat. You kind of have to go in head first to work in there, at least on a 25. Removing the foward floor panel would help, but that means removing the console first.

My 17 OR came with a thru hull pump for a live well that I converted to raw water washdown. It worked great when we were still but kind of sputtered while moving due to the clamshell.

Mine(2001 23'OR) is set up with a valve so the thru hull feeds the pump for the raw water wash down or the live well.

I can take pictures and get specific info off mine but it won't be until the weekend of Feb. 15th. Let me know if this would be any assistance.

I have a 98 Montauk and I installed a raw water wash down and through the help of a Y valve and 7 gallon water tank I also use it for fresh water.

I installed the pump inside the console with the hose fitting running out the side next to the fire bottle. I ran the hose down the middle tunnel. I did not drill a hole for water pick-up, I just passed the hose through
one of the scuppers in the splashwell and tied the hose under my swim platform.

Everything looks nice and neat and it works great.

Ferdinando- I never considered a wash down on my Montauk. However I have some lobster pots which get very very messy, and I'm intrigued by your setup. Would it all be possible to get pics of your setup?

Let me see if my wife will help me with her digital camera I'm not to good at posting pictures. As I said you run a hose over the stern into the center tunnel into the console.

My pump is located in the upper right hand corner of the console (looking forward).
I then used about 3 to 4 inces of hose from the pump outlet to the fitting on the outside of the console and bingo you have a washdown hookup. I'll try to post some pictures and E/mail them to you.

Here's a link to pics of my 22' OR. Notice on the port side, transom bottom, a piece of SS sheet metal bent to accomodate the ShurFlo pump. This is one of their mag drive pumps with a built-in suction port for washdown. The washdown pump is located under the starboard gunwale. The pick-up tube is 3/4" pvc, cut at 45 deg., with coarse SS screen epoxied over the opening (it clogged with chum once before this fix). I inquired about the clam-shell pick-up at the local dealer...he said he had seen people drill through the "bilge-bait-well" aren and glass-in a "box" to accomodate this...I wasn't willing to cut mine up at this point since the setup I have now works very good.

I installed a washdown pump and ran the suction line out the stern scupper and down between the hull and the whaler drive.

My live well is set up with both a pump on a timer mounted to the transom and a high speed pickup.

A piece of small diameter PVC tubing is cut at an angle and mounted so that the end extends just below the transom,when on plane water is forced up the tube and circulates through the baitwell.I went one step further and ran a distribution header down to the bottom of the baitwell because I use it mainly as a crab hotel.

Fred- Thanks. Don't worry about the pics. No need for the inconvenience to you. I get the picture from you description and am inspired to do something similar. thanks though.

Duckduck, I have a 22'OR WD with the raw water intake & scoop-strainer installed on the starboard side of the hull appriximately 2' forward of the trailing edge of the transom. This puts the 3/4" threaded thru-hull in the starboard well just forward of my transom storage area. The intake hose runs from the well into the storage area where the pump is installed.

My installation would be pretty easy to reproduce, as the access is convenient and you don't have to plumb around interior obstacles. It also puts the water at the transom, which is perfectly convenient.

However, if I were doing this installation from scratch I would be concerned about the intake scoop effecting trim at speed, since it sits in a pretty critical part of the planing surface. It doesn't create a problem on my boat, but the whaler drive may compensate for any adverse effect cause by the intake. Also, although my system parts are like those described by lhg, I don't know if my installation was done by the factory. Maybe it was done improperly by the previous owner and the whaler drive was forgiving enough to compensate.

I pulled my wash-down system out in the course of checking for water in my hull and replacing all the thru-hulls. I'm seriously considering glassing over the intake hole to eliminate another source for water intrusion.

If I were in fresh water I definitely keep the system, but I'm in the salt - and I spend too much of my time trying to keep the salt out of my boat ;-)

Alex - Although it sounds like a good installation, I doubt if it was factory installed. On all Outrages that I have seen, 18' and longer, the intake was always in the starboard bow area, and pump in the console. If your console has the push-pull switch on the switch panel, adjacent to the compass light switch, labeled washdown from the factory, it would be original.

I did notice that beginning with the Reebock era boats, the washdown intake was near the transom, with a round, non-scoop type, intake strainer cover.
