I bought a Rule 1100 pump. 1100 gph nominal flow, 3.3 amp draw. I plan on using either a 4 AH gel cell battery that I already have for a depth finder power source or purchasing a 2 AH gell cell battery for dedicated service. I also bought a marine grade switch, waterproof fuse holder. When I discovered the potential problem with the lack of a check valve, I considered putting the hose in with a couple of bends to form a trap. I may still do that. What are you using for a battery? Thanks for the prompt reply.

What type of pump did you go for ?

Why don't you all just get the portable little pump sold at Boat U.S. and others for about $30. It is pretty quick at dumping water and runs off of three D batteries (if I recall correctly). The best thing about it is that it is compact,removable and has a long hose which you can hang outside the kayak. I would be very hesistant to make any holes through the bottom of my kayak. I do note, however, that I had a Nordkapp that had an exist hole on the side of the boat above the waterline. This was an awful Chimp handpump that was next to impossible to use. The handle was short and located right behind the middle of your back. Valley said another padddler was supposed to use it to bail you out! Anyway, I would give the batter operated, portable pump a try. It is also handy to bail out water in anything you left uncovered after a downpour! Personally, I don't see what's wrong with a small bucket or scoop - it will take out enough water to get you home, and it will never break down! As they say, no pump is faster than a scared man (or woman) with a bucket! - Scott Dana A. Dickson wrote: > > I bought a Rule 1100 pump. 1100 gph nominal flow, 3.3 amp draw.

That pump is not that compact. Its footprint is about the size of a hand with fingers spread appart. It only pumps 200 Gallons per Hour. Another drawback I found is that if you have a dry top and a neoprene spray skirt there is not any place through which you can pass the outlet hose. You have to remove your spray skirt to get to the switch and turn the pump off. The system I am installing uses a 500GPH Rule pump, since it is the only one that is reported not to break. I use two of those square 6v batteries for emergency lights connected in series; the idea of having a gel battery like big boats have, full of sulfuric acid gel, inside the hull was not appealing. I connected it to a float switch which I can strap down when I practice rolls (otherwise the float would fall back an turn on the pump every time the kayak is upside down). I tried using a bucket, which turned out to be a lot faster than the hand pump in a kayak with a large cockpit. Unfortunately is it useless if you have a Greenland style 20 inch cockpit. An electric pump for sea kayaking that is easy to install an operate, is one of the items that belong to the list of things that for some strange reason are missing from the sea kayak market, yet they are extremely useful. That list includes: airbags large enough to fill a sea kayak's for and aft hulls, liferaft with rigging and hydrodinamic shape, solid paddlefloat with rigging, spray skirt with pocket for radio and flares, etc, etc. - Julio *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************
Julio, Sounds like your pump is much more powerful than the small portable one I used to have. But you said the pump I described wasn't that small (you are right about the approximate size). However, aren't two 6 volt batteries much larger and heavier? The pump I mentioned IS relatively light (running only on 3 C or D batteries). I would hate to have the weight of 2 6 volt batteries with me at all times. More troublesome is the possibility of an acid leak if the boat flipped or was rocking alot. The pump I described is made to be totally submersible - not the same with your batteries. Anyway, I hope your system works. For now, I'm just using a scoop and a hand pump - low tech, but the batteries never fail! - Scott MacWilliams wrote: > > > > > Why don't you all just get the portable little pump sold at Boat U.S. > > and others for about $30.

I just have a self contained attwood portable, mounted behind the seat, with the outlet pipe on the pump plumbed in to a fitting in the hull. It runs from three D-cells contained in the pump body, and pumps ~ 200 gallons an hour. Drains my cockpit in a couple of minutes. Only great drawback is the switch is on the pump body which is difficult to switch off through a neoprene skirt. In extremis I reckon that I wouldn't be too concerned about leaving the pump running until I could pop the skirt to switch it off. I suspect that with your pump a trap in the outlet pipe is unlikely to make any significant difference to performance. My pump throws a horizontal jet about a foot and a half from the outlet port, and the outlet pipe is about a meter and a half long - most of which is wound around the pump body. I highly recommend electric pumps. Even my cheap little attwood portable is quick and pain free - paddle and brace while your boat empties. I think in water likely to throw a proficient paddler out of their boat, that unless you have someone to raft up with (in which case my choice would be the T-rescue I described a while ago - **much quicker than any pump**) then using a portable hand pump is unlikely to be very successful, and bailing a boat with a bucket is utterly ridiculous. A fixed hand pump is more realistic, but still has the drawbacks that you can't paddle and brace and is slower than even my cheap and simple electric pump set up. .... just my thoughts.
