Installing a Bilge Pump by Don Casey

Mount the pump

You must not place the pump in the bilge unrestrained. If it falls over it will suck air and burn out. Pumps must be fastened down. Brackets are available that attach to a stringer or other vertical feature, or you can epoxy a couple of bolts to the bottom of the bilge to serve as mounting studs.

Float switches must also be fastened.

Use smooth-bore hose

Corrugated hose reduces pump output by as much as 30%, so always connect the pump to the discharge fitting with hose that has a smooth interior surface.

Bends and long runs also reduce pump output, so make the hose run as straight and as short as possible. That may mean discharging the pump through the side of the hull rather than through the transom. However. . .

Place the discharge above the waterline

If the discharge is submerged when the pump runs, the ocean siphons back through the pump into the bilge when the pump shuts off. When enough water has entered to float the switch, the pump will eject it, only to have it siphon back again. This continues until the battery is depleted, then the water floods the boat until it reaches a level that gets the crew's attention.


The discharge fitting must never go below the waterline. If the fitting is through the transom, be sure it is high enough not to submerge when the stern squats. And if it is through the side of the hull, it must be high enough to remain above the water at the deepest angle of heel.

Use a thin-wall fitting

The through-hull fitting can further reduce pump capacity. To minimize this restriction, use a fitting with the largest possible opening.


Lead wiring up
It is essential to get the pump wiring out of the bilge as quickly as possible. Run the wires up and secure them so that they do not sag into the bilge water.


Don't skimp on wire size

A 3,500 gph pump will draw 15 amps, typically necessitating 10-gauge, or maybe even 8-gauge wire. Consult the ABYC Wire Size Table to determine the appropriate wire for your pump and length of wire run.

Use butt connectors and heat shrink

Crimp-on step-down butt connectors will assure a good mechanical and electrical connection between the supply wires and the pump leads. Enclose these connections in adhesive heat shrink tubing to make them water tight. You must slide the heat shrink over the wire and out of the way before you make the connections. Then center the tubing over the crimped connector and shrink it with a heat gun or by playing a flame beneath it. Be sure there are no explosive fumes in the bilge!

Connect to the battery

When you turn the power off to leave the boat unattended, you don't want to turn off the bilge pump. Connect an automatic bilge pump directly to the battery, not through the distribution panel.

Fuse the positive side

It is essential to have a fuse in the positive wire as close to the battery as possible. Some switch panels (see below) include a fuse. Otherwise join an in-line fuse holder to the battery end of the positive wire using a crimp butt connector.

Install terminal fittings
o not strip the ends of the supply wires and loop them beneath the battery terminal wing nuts. Install crimp-on ring terminals the proper size to fit the threaded posts on your battery. Use a copper washer-not steel-between the wing nut and the ring terminal.

Three-way switch

If your bilge pump has a separate float switch, you may want to wire it to a three way switch that allows you to select automatic, on, or off. Be sure to support all wire runs at least every 18 inches using cable clamps or ties.


Two pumps

A bilge pump big enough to deal with a real emergency will do a poor job of keeping the bilge dry because the water in the discharge hose drains back into the bilge when the pump shuts off. And a big pump requires a big hose.

The ideal bilge pump arrangement is a small (400 gph) automatic bilge pump mounted in the sump to dispense with rain and shaft-gland leakage, combined with a high capacity pump (3,500 gph) mounted higher to deal with more serious ingress.
Stepping the discharge hose from the small pump down to 1/2-inch minimizes the backflow from the hose when the pump cycles, maintaining a dryer bilge. The large pump can be wired to a float switch if you prefer, but I think a manual switch makes more sense. An added advantage of this bilge pump configuration is that the high-capacity pump sits high and dry, extending its life indefinitely.

Default a bit of caution is warranted

Congrats on the new skiff, I'm in the process of buying one myself as it turns out. Keep in mind that recreational boating is one of the more dangerous activities that Alaskans participate in, and more than a bit of caution is warranted. The local Coast Guard Auxiliary will have lots of good information on required safety equipment and procedures, it's a good place to start. Even if you boat is small enough not to require a lot of gear, it's a good idea to be over-prepared rather than the reverse!

Best bet is probably to find a buddy who knows what they're doing and tag along with them for a bit, get to know the ropes, so to speak.

What make of skiff did you buy and the motor size of it? I was wondering on the type you all use in Alaska for salmon and halibut fishing on being able to get where you can catch them.

Smile Thanks all

Thanks for all the advice--appreciate it. Got my bilge up and running this weekend but still need to mount it securely.

To answer Chevy's question; around here a 16-18' skiff will get you around inside waters for halibut, rockfish, and trolling for salmon. Whalers aren't heavily used anymore (no longer in major production) but any V-hull Lund/etc will work. As Rotor said (and thanks) caution is advised--very careful attention must be paid to weather and tides, and emergency equipment is a must for preparation. Weather changes so quickly it's scary.

Even though I've been boating here for several years, I learned a first-hand lesson this weekend. The wind and waves come up SOOO quick--found myself out in mid-channel instead of sheltered behind an island when a squall came up and it was very bouncy and un-nerving, though I was safe--as long as my motor kept running!

Still I'm sooo happy to have a boat!

I have a buddy who is a charter captain and I just might be getting the inside scoop on a few choice holes pretty soon...he's awesome! I still like getting out to the real water more outside a couple times a year, so I go with him and help pay gas, etc--we both do our subsistence fishing for halibut/salmon on those trips. Got a 80 lb halibut last year!

That type of info is sacro-sanct so I will be on the lookout for a few trustworthy friends to take along.

Thats why there is winch on the front of her 4x4 S10 Chevy....you tow 'em to the beach and winch 'em in

you don't want an 80 pound halibut in your boat unless you shoot it with a 44 cuz he'll trash your boat...

and...80 pounds isn't even that big for Prince of Wales Island

Small depth charges work well. Then while they are unconscious you quick loop a rope over their tail. When they come to you go for a ride...sometimes up to an hour. Then when they have exhausted themselves you pull them in close to the boat and tie off. Now you just beach the boat and drag them up the beach with that winch mentioned earlier!

Just kidding!

Default now pull the other leg...

Alrighty now Rance, now pull the other leg...

Eighty pounds is a respectable halibut, but certainly not a BIG halibut. Truely big ones go easily in the multiple-hundreds, I believe the derby winner in Homer this year was about three-fifty or so and the state record is around five. With fish that size, you DO have to worry about what happens when (or IF) you finally get them out of the water. If your boat is big enough (like a commercial fishing boat), just bleeding the gills or drowning them in air will do the job. If it's too crowded or too small to risk it (or you just like shooting things) you can use a "bang stick" or just shoot it.

Problem is, not too many folks know EXACTLY where such a big halibuts brain is, and not every halibut feels dead enough to stop moving even after it's been shot a few times. A halibut in the multiple-hundred pound class can easily injure or damage when it gets irate enough (what with you trying to kill it and all), so it's not a minor concern. I suspect that since it's so dang much work actually getting one that big into the boat, there's plenty of chances to shoot while it's at the surface but still in the water.

And on the soapbox side of things, you need to consider if you actually WANT to kill a fish that big. Yes, it's probably a once-in-a-lifetime fish. Yes, there's a LOT of meat on a fish that big. Yes, you might just win a bunch of money if you remembered to buy a derby ticket. But...keep in mind that any halibut over about a hundred pounds or so is always an older female (they get much larger than the males). Older fish in that size class contribute disproportionately to the reproduction of the species, and the bigger they are the better they lay eggs. A three-hundred halibut doesn't lay three time the eggs of a hundred pound halibut, it's more like ten time more. She's a proven survivor just by having gotten so large, and more likely than not she lays the best quality, healthiest eggs in addition to the larger quantity. Thats a LOT of future little halibut you're filleting there with that monster.

Another thing to consider is just how much halibut can you (and your friends, and your relatives, and your neighbors) actually freeze and eat in a reasonable amount of time? Even when you vacuum pack it in high-quality freezer bags, you've got maybe a bit over a year before you're looking at chowder-grade, freezer-burned fish. It's less if you're just zip-locking them. I love halibut, but could I eat my way through a mammoth like that in a year?

Also keep in mind that fish that big can sometimes get wormy, something you almost never find in smaller fish (it's mostly an esthetic issue, cooking kills them). Fish that big have such big fillets that you have to butterfly them three or four times to get them to reasonable cooking thickness, which is a lot of additional work at the cutting table when you're already looking at a HUGE job. The oldest and largest fish are also somewhat mealy-fleshed compared to younger and smaller fish. It's still decent meat, but not quite as good as say...a fifty pounder, which is coincidentally about the largest fish the better restaurants will buy.

If it sounds like I'm trying to talk people into catch-and-release on the "big mamma halibut", well...I am. I'm not usually a proponent of that practice, as I think the more appropriate term would be "playing with your food". I don't fish just for fun (though I do enjoy it) and consider "catch and release only" streams to be essentially fished-out for all practical purposes. I see no point and certainly no need to repeatedly haul the same poor surviving trout back and forth until they finally die just for some "fishing purist"/snobs enjoyment.

What I do consider important is the future survival of the species that we use for food, and it's economic impact on the state. The Alaska/North Pacific fisheries are perhaps the most logically and scientifically managed in the world, but that's not saying they're perfectly run. Halibut is by all reports a very robust and healthy species overall, but there's a LOT of evidence that the easier-to-reach, near-shore halibut fishery is getting more than a bit stressed in a lot of the more popular spots. Charter captains and sport fishers are catching smaller and smaller halibut every year, and going further out to do so. While the halibut by-catch of the commercial trawlers reportedly exceeds the entire sport fishing quota, it isn't going to benefit the hundreds of charter captains and the related businesses that rely on that traffic. It would certainly help if more people considered letting the "big mamas" go with just a photo or two instead of the gaff and the bang stick.
