Bilge water mystery

I had occasion to use the Whale with a full bilge after developing (it turned out) an airlocked Rule. It was far offshore, and although the bilge was empty in 20 or so pumps, I was astonished at how much work it was, and at the prospect of having to pump continuously in the event of disaster.

A crew could keep at it, in shifts. For a couple, or for a singlehander, tough duty.

The handle needs to be longer than mine, which is about 2 feet: nice for storage, otherwise a bear.

I had thought about this scenario recently. after a little web surfing, found that you can buy household submersible pumps that use 12v:


My wife also recently purchased a collapsible garden hose that stores in a small pot. I was thinking this, combined with the pump, could be a good backup system to get water out in a hurry while finding a more permanent solution.

PS. I have 110 VAC version of one of these pumps and it saved us from a lot of water damage at our house when we came home to find a burst supply line on a washing machine.

Just received this in an email:

A Dry Bilge is a clean, odorless bilge.
Rule now offers the best, most effective method of removing almost all of the water in your bilge, leaving 1/8” or less, keeping your bilge fresh, clean, and dry.

The 360° rotation of this pump head gives this pump true installation flexibility.

I had a similar issue and finally cured it by tightening the keel bolts. No need to drop the keel, but tightening the bolts seemed to seal things nicely.

Looks like a good alternative to the submersible rule pumps . Even with no dips in the output hose , my rule 800 airlocks occasionally. The submersible/centrifugal pumps are not self priming , so if you let the output drain into the bilge , then manually dry it , the pump can airlock and fail to work . Unfortunately, I don’t have any room near my bilge to fit a jabsco diaphragm pump. It would have to be located back in the coffin under deck or engine compartment.

Rule's "Typical Application" diagram shows the pump remotely located out of the bilge as any diaphragm-type pump would be, so whether it pumps down to 1/8" or not depends on your strum-box or hose setup at the inlet. 240 gph is a pretty slow pump rate.

Result of this discussion I happened upon this device, which claims to remove all residual bilge water. Don't know it would fit between our keel bolts, but it might.

the pump

I guess it boils down to vacuum vs. pump. During my weekly bilge FOD, I sometimes find "stuff" that may be easier to block a strong vacuum than a screened pump? The Arid video does not show a screen..Just thinking.....

Also the Rule dry bilge pump is $243 !

I accomplish this same dry bilge outcome with the same $50 fluid extractor I use for oil changes. It will pretty much remove every drop of water, whereas this Rule system still leaves 1/8". And it's not another system to install and maintain.

As per Loren’s endorsement :) ..I bought a turkey baster from Amazon.. upon opening, my wife said “why don’t you take the old one to the boat . I need that new one with readable graduations” . So , I said ok but let me test them first . Both seem to work well with a shallow Pan of 1/8” or less of water . In fact I give a slight edge to the old one ....
