Washdown Pump Install and Fire (In that order)

[Capt. Bob]

Bob, get some rust converter at Autozone.

Something such as this?

Yessir CB.  It does exactly what is says it will on the can.

I used to rep that line. Sometimes I miss it, sometimes I don't. This is such a unique product that works really well in a lot of different situations. It was and is still used in the auto industry to coat the insides of the pillars on cars and trucks to keep from rusting from the inside out.

Well guys.. Had the 245 out in the gulf on Saturday and I am glad to report the new pump worked flawlessly!  Ran her most of the day in bait mode and our livies did very well.  She also pushes a serious stream from the hose.  Very pleased with performance and how quiet it is..   Now if I can keep her coated she should last for a while..  Hope you all have a great holiday weekend!!

This one went into the cooler!

Bruce, that's when it's time to toss the skis in the water and have some fun!  Looks like the morning conditions in July/August...

[Capt. Bob]

Yep, I missed both days this past weekend. A rarity up here this time of year.

Good to hear you like the pump. It works well for my app so it's always nice to see a member who finds the same.

It really does spray (wash down) well for a "combo" unit. :o  I think members would be surprised.

Good luck and nice fish.

Speaking of Shureflo pumps for wash down and for baitwell has anyone had any luck or experience with the shurefloe baitwell pump (impeller type) that also has the pass thru outlet below the pump to attach you wash down pump to. I like the idea of only one thruhull for both pumps and this pump seems to be the answer. Just looking for some input from y'all on this setup.

Yes, that is the way to do it

[Capt. Bob]

Do you need an extremely powerful wash down pump?
Do you have a live well bigger than 35 gals?

The Bait Master pump works pretty well IMHO and BT seems to like its operation. You only have one pump to contend with and you retain just one hull penetration.
I realize many members like separate pumps.

Just curious.

[gran398]

That is a good point, one pump for both applications.

On the other hand, with a separate impeller baitwell pump, you get a higher flow pump with lower current draw at low additional cost.

Probably why Bob asked about your baitwell gallon capacity. Either way...only one 3/4 thru-hull is necessary

This is very true and arguably the best reason to go the two pump route.  
My 500 Rule live well pump had about 2 amp draw (as per manufacturer) while my Bait Master draws about double and flows about half (on paper). I haven't actual numbers but it is a strong consideration if you do a lot of live bait usage. Pin fish will stay alive in a Porta Potti so the flow has not been a factor in my case.

I use the wash down more than the well (artificial bait freak) so it works well in my application. Knowing your style/bait sustainability is the key.

Good luck.

I would definitely go with the two pump set up. The impeller pump gives a ton more flow at less than half the current draw, my last boat had a 3/4 inch inflow and a 1 1/2 in outflow. In order to keep the bait frisky a large water turnover in needed. Most of the bait we have here in Greenies (menheaden) and if you get a buch in the well you need a really fast water turn over or they will start to die quickly.i am putting 800 GPS on a 35 gal well. Also I am not sure that a diaphragm type pump like a wash down pump is rated as a continuous duty pump, I was under the impression that they were ment to pressurize the line then shut down and hold the pressure whereas a impeller pump is built to just give a lot of flow

True in many cases but it isn't the type of pump that rates its duty cycle but rather the motor itself. A number of the Shru Flo wash down pumps are powered by an intermittent duty motor and perform as you have stated. The Baitmaster pump addressed above is a diaphragm style pump powered by a continuous duty motor. Like other pumps of this type, it uses a pressure sensing switch to control usage but allows the pump to operate continuously when it senses unrestricted (like in the continued flow of a live well)  operation. When used in a wash down mode, it shuts down after pressurizing the line to a preset psi and restarting when the pressure falls below a given psi. In this case, operation is the same for both pumps.

It is a compromise in both scenarios but fills a need for those (like myself) who like a live well but use it on a limited basis, like having wash down capability and prefer using only one pump for both. If a live well is a necessary factor in fishing style, then as you and others have stated, the impeller circulation technique is definitely the best solution based on battery current used for flow and bait sustainability.

Excellent synopsis CB.

800 gph on a 35 gallon well is perfect. You want good strong flow, but you don't want to blast a fragile bait either.


One thing I've always found amusing is the diaphragm pumps are rated gallons per minute....when you do the math, most of them come in around 200 gph....

Here's an example of a top drawer pump at 240 gph.

You make a good point Scott. The numbers don't lie but in the case of a wash down pump, you are looking for pressure as opposed to flow. A bilge (impeller style) pump is concerned in getting that excess water out and doing it fast (somewhat anyway). That again is a compromise with the Bait Master. It flows less and uses more current :(  to do so but it also puts out enough pressure to wash blood, guts or chicken bits from the deck.
