CB, keeping the livewell areator head shut off should give you the full effect at the washdown spigot...

Indeed it does Bob.

I have a PVC ball valve located at the live well intake and a hose bib located under the port gunnel at the stern (pics later).
When running the well, the ball valve is open (duh) and the bib closed. To use the wash down, I close the ball and open the bib allowing the full pressure of the washdown section of the pump to be realized. Reverse when done cleaning. Rather easy since my well is currently on the deck. The bib allows me to relieve the pressure on my coiled hose, thus (hopefully) extending its useful life.
Relatively cost conscience and has been a very useful device. Hope it lasts awhile.

PS..... helping hold down costs was easier due to a fellow Member.

Thanks Jessie.

Slippery, I don't think I've ever seen a seachest in any boat smaller than a 50...

I don't think I've ever seen a seachest.  Pls explain.

A seachest, simply explained, is a fairly large hole in the bottom of the boat that fills a box (or "chest").  All the pumps live in this box, hence the use of bilge pumps as they are designed to be submerged and be happy.  Protruding from the sides of the box are all the t/hulls for the hoses of the various features you are feeding, be it a livewell, a washdown, a raw water sink, whatever.  Actually, I think either YF or SeaHunter (one of those big buck boys) is doing them on like 36s and 38s...

The fishing boats using them don't have a hole in the hull like a large yacht would, they use a through hull with a seacock that feeds the box. The pumps go in the box from there,  it can really be any size, small or large.  More and more smaller boats are using them, contender, seavee, invincible, yellowfin, etc. Would be interesting to see a small box with two pumps in our size boat. Would definately be custom.

Slippery, you went and found pics.  I was too lazy...

Don't confuse this with another device that reduces holes in the bottom of a boat, an intake manifold, where one fairly large intake feeds several smaller outflows.  A prime mover that uses a lot of water can create suction and air locks in the lesser systems...

10-4 on the strainer before the pump for the livewell, Its really needed and mount it so its easy to get to. I ran the magnetic drive shurflow pumps for years and am not impressed, they are loud and don't seem to throw as much water as a regular pump . Now I run tsunami pumps (800gph), they are not the best either but are cheap and easy to switch out. I have also ran the rule tournament livewell pumps, on everyone the impeller has rusted off in less than 6 months. No matter what pump you choose it will burn out.  I think the cartridge style pump is the way to go as they are the easiest to switch out. Simply carry a spare if you run just one livewell pump.
 I have 3 thru hulls in my boat with one for the washdown ( 5.5gpm) and two completely seperate livewell pump systems feeding one 43gal well.  For the wash down go with 5gpm min if you want it to have any kind of pressure or at least spray harder than you can pee.
I know you don't plan on doing the kind of livebait fishing I do but I don't see any disadvantages for having 2 thru hull fittings keeping the washdown and livewell seperate only the cost of the parts.

Wow, that's pretty bad a$$...

Matt, much appreciated. To the extent I won't use the livewell much....maybe 6 times a year...gonna keep it simple and run the two in-line.

I like the idea of separate feeds/separate pumps for your daily use...smart.

On my app, the cartridge livewell 800 with two outlets should do a good job for my needs. Like the self-primer behind the livewell pump....should minimize air locks.

CB...will go with you and  SB's thinking....on-off at the livewell. Thanks guys

[Aswaff400]

Or run two pickups...

While that would certainly work, the idea behind the dual port is to eliminate the need for a second "hull penetration", as ABYC likes to call them.  And one less hole in the bottom of the boat?  Not a bad idea...

i removed my old mushroom head t-hull for the washdown and installed this setup, plumbed the washdown into the port on the pump, didnt have to drill any holes. other nice part is the open through hull would easily clog the strainer with grass within 30 minutes on the flats. so far with the new set up, 3 trips out, nothing in the strainer yet...

[seabob4]

Sweet little set-up Aaron!  Now once you installed, how much fun was it to get everything tightened, yet the ports, the alignment, the shut-off handle where you wanted it?

I remember this one I did on the Doc's 22-2...



To get the handle to swing, clearing the bilge pump (not going anywhere), clearing the transom (not going anywhere), getting the elbow, the shut-off valve, the pump ports to line up?  Jerzus Christ!!!

But it came out OK...

[Aswaff400]

got everything lined up pretty good and works great so far, the strainer is in an easy spot to get off, and the valve handle is easy to open and close...

[gran398]

VERY slick Aaron!

We don't have grass up here...but since you guys think should run a strainer...as long as it doesn't kill the flow...am all about it.

Install a strainer Scott.  I just may put one in the Doc's 22-2, but he hasn't said anything yet, and that was almost 2 years ago....

But Aaron fishes REAL skinny!!

one eye on the water, the other on the tide table even surprised my dad on Christmas on how skinny she'll float in

No Problem!  Happy to hear you got good use out of it.  I should be running into more goodies soon... I'll keep you in mind.

You doing a spray head feed in your livewell or a directional feed.?
So many choices
