I have to agree with Danny. I mounted a Whale Gusher and it does a much better
job of sucking the bilge dry than any of the centrifugal pumps that start
picking up air earlier and then cannot pull any more water out. Those always
seem to allow a lot of backflow, and a backflow preventer valve only adds
restrictions, thus slowing the flow.
Though the Whale Gulper is not rated nearly as high from a gallons per hour
basis, judging from the time it takes to empty a nearly full bilge I get the
impression that its real life performance is nearly as good as the small
centrifugals.
Just my $.02 worth...

Subject: Re: Stus-List recommendations for a small bilge pump
Oh And on the Viking, I used 2 Whale gusher pumps. I mounted them High and
dry in a locker and was able to suck the water out with hose led into the
bilge. If you can make the pump you high point and go gravity from there, you
might actually be able to get the water level down very low with little
backflow. I have to say, it is nice getting the pumps and the wiring out of
the bilge. I plan on doing this same setup someday on the tartan.

The automatic bilge pump in Cat’s Paw is fairly old (2011) and although it
still works fine, it requires a separate float switch (also old) which is
located in a shallower part of the bilge so leaves about 4 inches of water at
the pump when it turns off. I am looking for a replacement that has the water
level switch in the pump. There are lots of these for sale, but what is the
list’s recommendation? The old pump is a Shurflo (sp?) 355-100-00, rated at
1000 gals/hr, - the label says it draws 7.35 amps (but I haven’t measured it).
Is Shurflo even made any more? I see Rule pumps and lots of brands I have never
heard of on line. The automatic pumps I found online leave about 2 inches of
water - is that the best we can do? And what pumps last well? Advice welcome.
