BIG challenge with retrofitting a new Bilge Pump

So I'm restoring/repowering a 28 foot sloop -- I'm actually enjoying it as I knew nothing before I started. Now I know more, but I'm on steep learning curve. The boat is Italian made.. built in 1983. She sits in a deep water slip everyday. Here's my problem.... I'd like to put in an automatic bilge pump with a float switch, currently I only have a manual bilge pump. The problem is every bilge pump I look at has the fitting on the side .. because the bilge is small, the fitting has to come straight up off the pump, not off the side. Hate to have all my hard work wind up at the bottom of the river. Any ideas are most appreciated.

Re: BIG challenge with retrofitting a new Bilge Pump

You might want to consider a diaphragm pump like the Whale Gulper 220. Most bilge pumps are centrifugal pumps and they need to be immersed in order to work. A diaphragm pump is self priming, meaning that they can suck water up a hose before pumping it overboard, however they don't pump as much water as a centrifugal pump so don't rely on them for emergency pumping situations.


I would use it with an electronic switch like the Atwood S3. The switch will keep the pump running for a minute after the water level has dropped below the sensors thus clearing your bilge completely.
