First post here, I've been on the forum for a few months now and have gotten some really useful info from it. I'm currently having a boat built, and am looking to put in a high volume raw water washdown. I really just want a washdown that pumps alot of water without any high pressure spray nozzle. The washdown will be mainly used for coring out fish where it is nice to have a lot of water at a low pressure. I have seen alot of boats with this type of washdown and was wondering what pumps people typically use for them? I am thinking about just getting a big livewell pump (1600gph) and using it, but I am curious as to anyone elses input on choosing a pump for this type of washdown.

Take a look at Pacer pumps, they are hydraulically driven or i think you can get them with a electric motor but not 12 volt. They pump a ungodly amount of water like 250 gal/minute(yeah that much!). I had one on my gillnetter for a net washer to blow jellyfish and glacier silt out of the netting. I know they are using them on lobsterboats for tank pumps and i'm thinking they are powered by the steering pumps.

Sounds like you're talking about a Rule 17A

Good pump, I have one on board. Hassle free and only needs some wires to run. Probably will go with something more heavy duty on my next boat (Pacer) just to expand the possibilities. Plus if (when) something goes wrong you can just yank it out and pop a brand new one in place in a matter of minutes. Whichever route you decide on following I would suggest a strainer of some type, either a scoop strainer or inline strainer, just to reduce the amount of seaweed related headaches.

I have a Rule 17A (as mention & pictured by Travis)
I have a 3 way valve off the pump, one way to my livewell, the other to an 1 1/2 hose on the deck.
3800gph, lots of water.
Only down side of this pump it draws some amps !
Put a reducer on the end of the 1 1/2 hose to 1 - 1/2 inch lots of pressure !
I also have a typical wash down that I very rarely use.

I shelled out my original alternator last year when I put the 17A on board, after 11 years the engine was no longer stock. It did put up one hell of a fight though, didn't go down until the last bit of the season.

Heart breaking moment.

X3 on the rule pump. I have always used them for washdown and livewell. I have 2 on my current boat. They last forever and pump great volumes of water. You just don't want to leave them running for long periods of time unless you have a generator and charger or you leave the main on to charge the system. I believe they draw around 10 amps when running.

The 17A is exactly the type of pump that I was looking for, just ordered one. Thanks

I get 4-5 years out of a pump.
Had to replace mine 2 weeks ago. $160 delivered found on line.
When running the boat a distance I shut the pump off.
The clam under the boat of the thru hill pills the water in same as having the oimp turned on.

Placement of the Rule 17 is key to getting good use of it, they will push a good amount of water but will not lift water with out a good priming. The closer to the seacock the better. I have a Rule for my below deck tank's pump out and a 2 inch pacer hydraulic driven off my power steering pump for deck hoses.

Overkill, is 100 percent correct when he said it has no power to lift water...on my boat the deck is so high off the water line that the pump doesnt prime right away...and also you should keep a eye on live well levels when you shut it off it will siphon the tank back out

We used an engine driven pump for our deck wash down. Which was two corrigated pool hoses that each had a valve at their output to regulate flow. We also had it set up as an emergency crash pump with a T and a valve at the pumps seacock
