I have no doubt. Great boat. Nor as good as a Catalina 400, but still a great boat (snicker).

They maybe "junk" and a scared man with a bucket maybe be the best bilge pump but the manual pump(s) would get that last little bit of water out of the bilge which the electric pumps don't. A bone dry bilge is a nice thing. Don't get why both worked in past and neither work now. Was told something about a one way valve in them which maybe fouled. Haven't taken the pumps apart yet but that maybe next step unless someone has further thoughts.
Mine has a "check valve (really a one-way valve)" at the very end of the tube. It is a screw on, but I cannot imagine how that type of valve would fail. Have you tried putting some water in a small bucket and seeing if it pumps it out?

Brian

PS I would make sure mine worked too. But being a new boat, I would be on the telephone with Outbound!!

Re: Bilge Pump Blues

Anytime there is a change in component performance, it is helpful to look at what changed since it last functioned correctly. You said you were winterizing the systems. Did you take anything loose, break any seals?

Replaced that with straight wall hose, still didn't work. Then found no suction at the pump. Put in a new Jabsco last night... problem solved. What are the odds that when I discover a really bad hose... the pump would finally die the same day I replace the hose?

I replaced the float switch (which was also shot) and now have a totally new bilge system. I think I will yet install a submersible centrifugal pump and little higher.

This is fun!
No.

Install the centrifugal at the same height (bottom of bilge) but put the float switch higher with an alarm.

My primary pump is a diaphram which is great because it has a strainer, is self priming, and can overcome head pressure. I also use a "check valve" at the very bottom of it so that it can really pull the water out. THe negative of diaphrams is they do not move as much water. THat is where my centrifugal comes to play. It also sits in the bottom but with a higher float switch. SO when that one kicks on, I really get a lot of water moving (and I know there is a real problem).

You can purchase the float switch with alarm. I highly recommend getting insurance with it (if you buy it from West Marine). These things are renowned for failure since they changed to the new switches.

HELP! Why don't the whales work?
DUmb question, but are you sure they are clogged? For grins and giggles I tried mine a while back. It took a long time to get water to come out because they hold such a high volume in the hoses.

Re: Bilge Pump Blues

Outbound,

You can get a rebuild kit for them, but frankly they are junk. Other than for getting rid of very minor condensation no one can use a manual pump long enough to make any difference at all. Time is better spent trying to fix the problem. So they tend to get ignored, because they are a throwback to when there was nothing but manual pumps.

Re: Bilge Pump Blues

I share your obsession Dave. I was a submarine sailor in a previous life and I tend to overkill maintenance and repairs. I forget that I (hopefully) don't have to take this thing down to test depth. Sometimes my wife will say Rob, is this a submarine problem or a sailboat problem?
