Low profile electric bilge pumps.

I am looking to install low profile self contained automatic bilge pumps in the engine bilges of a 60 ft cat. I have no experience with low profile pumps.

Defender lists a Whale SuperSub Smart IC and a Rule 900S LoPro.

I'm looking for recommendations of any good units and comments on personal experience.

Re: Low profile electric bilge pumps.

Can't help you with personal experience, but whale makes a good product, generally. I use their shower sump gulper.

If you have self contained engine bilges, why a pump? They are designed to capture and retain a fuel/oil spill.

I had the whale supersub smart ic, well designed. I liked it but it lasted only about 2 years.

I want a self contained pump. The float switch is in the same housing as the pump.

Thanks bristolbob. Perhaps I'll try the Rule pending other recommendations.

Re: Low profile electric bilge pumps.

I use the Whale SuperSub too. It is reasonably good. Lasts 2 or three years at best. Sometimes gets stuck on, sometimes doesn't prime until water gets deeper. It's job is do remove the rainwater that makes its way down the inside of the mast. The serious bilge pumps on the boat are remote diaphragm units...up out of the bilge where they can survive much much longer.

Are the diaphragm pumps electric or manual?

The diaphragm pumps I wrote of are electric. I recall also Whale brand. However I have two manual diaphragm pumps as well which I hope to never use in haste.

I think my question was misunderstood. If you have contained bilges beneath the engines, they are designed to isolate a diesel or oil spill. If you have a float switch of any kind, it will automatically pump this out. I presume you're pumping overboard, therefore, my question.

Perhaps you have a different setup, but I would have thought a 60 footer would have isolated engine bilges. If they are isolated and you get water in this compartment, where does it come from? That may be a better focus.

Chas,

I have use the Whale Supersub pumps on 2 different vessels with no regrets. They were used in shallow areas where nothing else would fit. [Including our current boat...]

Do they have stamina? I installed one in the sump of a buddy's house basement on the US East Coast as a battery back-up to his 110VAC sump pump in the event of a power outage. His 110VAC pump died 3 years ago. The Whale is still going strong... [His pumps run hourly 24/7/365...]

However they are certainly not crash pumps by any means. But they do a great job of keeping low profile areas nearly dry. [Properly positions they will pump out all but the last ~3/8th inch of water...]

In case this is helpful...

Cheers!

Bill
