installing a raw water washdown?

[JR13]

Greetings all. Just looking for a little advice from some who may have done it before.

I have a 2000 Angler 20 ft cc that I bought earlier in the summer. I like a ton, but it didn’t come with a wash down pump and the bait well requires you to fill it with a bucket.

What I would like to do is install a wash down pump with two outlets, one that I can run to the bait well (which sits in the back corner, under a "jump seat" and one that can work as a standard hose.

I would also not like to have to drill through the transom or install a seacock if I don’t have to. As i dont really want to have to her out of the water. Maybe in the off season.

Here's what I’m thinking of doing...the way my boat is designed, there is a goodly amount of room and an access hatch behind the live well (there’s currently an aerating pump there now) I was going to install standard 5gpm pump (I understand I can get a decent kit for around 200 bucks, but suggestions for brands welcome) Then keep an input hose handy and just run it out the scupper when needed? I will then put a y adapter on the output hose and run one to the input of the aerating pump I already have, and one that would run out to a small hose for cleanup. There appears to be enough room to store the whole thing back there.

I was just wondering if this is possible and if anyone had done something similar and had suggestions. Googling, I've found threads from folks who had done something similar, but was looking for first hand advice

Thanks in advance.

16' CC with similar options. I've been contemplating a section of PVC piping over the transom and then down into the water. That way I can slide it up and down in and out of the water. Or remove it all together when I know i'm not going to be using the well.

Basically, putting a U that fits tight up against the transom on both sides with the input fitting below the waterline on the outside. Have gone no further than plans in my head FWIW. (#$119)

I've seen a pvc configuration over the transom somewhere (THT?) but I'm pretty sure a hose out the scupper won't draw while underway. You'll also need a pump that will self prime to the height of plumbing over the transom. If you don't want a thru-hull (Why don't you want a thru-hull seacock?) I've seen some solutions where the pump is installed on a temp bracket outside on the transom. That might work out

One thing is a livewell pumps are typically high volume, low pressure, continuous run while a washdown pump is low volume, high pressure and designed to be run intermittently. I've a sureflo 850 baitwell pump that I use for both purposes but it really lacks as a washdown. No power what so ever even though it moves a ton of water per minute. Next spring I'll add a dedicated washdown pump and be done with that.

using the scupper isn't the greatest idea for two reasons. As stated above, you won't pick up water very well when underway. second reason is it's just not a great idea to plug your scupper. If you take some water, it won't drain out the way it should. Keep your scuppers clear.

That said, there are some options on this site for transom mounted pumps.
www.livebaitlarry.com It's a simple system, though not very tidy. But it will work and you can even consider it temporary.

as mentioned above, "double duty" pumps don't do the best job one way or another. The best baitwell pump must be mounted below the water line and the best washdown pumps don't hold up well with "continuous duty" (even if they claim to). The washdown pumps also, as a rule, draw much more power.

this might be more than you needed. But I just went through this, so...
The best set up, IMHO would be to go through the hull with a good bronze mushroom thru-hull, topped with a good groco seacock. Then, over your mushroom thru hull, add a scoop strainer to pick up water when underway.

You can opt for a one piece "hi-speed pickup" that screws directly to the seacock, but I prefer the separate strainer. The reason is that if something were to strike the pickup, it would only take off the strainer, protecting the integrity of the thru hull assembly. If it were one piece, striking something could tweak the whole thru hull. Use a backing block when you attach the sea cock.

on top of the seacock, you can attach a dual port livewell pump. The top port gets plumbed into your livewell, and the bottom port gets plummed to a separate washdown pump. I use a Jabsco par max 4.

Run your washdown to a quick connect and you're in business.

good luck

Good advice from seemingly knowledgable sources. Im just not terribly handy and the thought of drilling anthing through the hull scares the crap out of me. But it sounds like its a pretty managable off season project. Probablys just suck it up for the rest of this season and use my 30 gal bucket with a filter and a bubbler for the rest of the year. Thanks again.
