Should I leave my auto bilge on? How much drain does the light have on the battery? I only have one battery and will not be on shore power to recharge for a few more days. I have yet to see any water in the bilge at all..... I know what most are gonna say, or at least think I do....but interested in your opinion.

In the water? leave it on. Only draws energy when engaged. It's just a switch.

It's fine if you get rainwater in the boat. The pump will remove the water and shut itself off when finished.
If however you have a leaky hull fitting, water will continue to leak into your boat indefinitely and eventually kill your battery. The pump will only forestall the inevitable. But that could be just enough time to save your boat.
If you're in a marina, call the yard boss. If you're on a mooring, you're on your own.

My switch has three positions, On / Off / Auto. Auto allows the pump to turn itself on if the float switch tells it to. This is the position I leave it in pretty much 24/7/365. Other than testing the pump, I've never used it in "On" (and hope never to), and I'd only turn it to "Off" if the boat was up on the trailer. Also, my switch only turns on the light when it's actively running, not when it's in "Auto".

Like Sten said, if the boat's in the water, you want to have power to the pump if the float switch engages.

I may have mine wired incorrectly but when I installed it I ran two hot wires direct to each battery with in-line fuses. I cannot turn off the automatic sensor. I did install a separate switch to manually turn it on. The only way I can turn it off completely is remove the in-line fuses.

Gang, where is the best place to place the bilge pump? We all refer to "the bilge". It's not clear to me where exactly that is. Under sink?

thanks,

dave

Above the keel. Lowest point in the boat.

True bilge pump story. I have a Honda generator with a wired 2600 gph bilge pump and hose ready to go should the worst happen. I told two Swedish cruising friends about my setup. They later became Captain and Stew for a Danish billionaires $5.5 mil Oyster 62. My big ass backup pump never left my friends mind. One day he decided to buy a big basement sump pump at a hardware store. 300 miles offshore from Greece, water started coming in. A thru hull was bolted to a plate which had separated from the hull. Water at ankle depth, but not up to the generator yet, my friend plugged in the basement sump pump and saved the boat. I get free beer for life whenever our paths cross.

The new automatic bilge pumps eliminate switch problems and are really reliable. 500GPH for $50. Wired to a hot and you are done.

<< new automatic bilge pumps >>

I used a rhule and it rocked. great solution, reliable. worked great. I used on in the front of the power boat to remove rainwater. Had a solar panel to keep the battery up.

I could step up on the front of the boat and it would kick on so we got to test it a lot. Nice not to have to worry about cleaning a switch/float.

Tweeet65 - here is a link to an easy-access bilge plate mod. The bilge is under this plate in a fin-keel boat. Same location but different arrangement on the other hulls.

Mine is a cat 25, a977 swing with a dinette plan. The only under floor access is a round plate and it doesn't appear as though there is room in the area (height) for the rule pump I got. I thought I would locate the pump under the sink and plumb it to the sink drain line.

Under the sink or the hatch below the starboard quarter berth is a good place on a swinger for the pump, but run the discharge hose to a designated through-hull on the transom. Also consider backflow prevention. There are many different opinions on how backflow should be handled. I’m sure someone will add their thoughts to this. I have the discharge hose loop well above the through-hull, and have never had any problems.
