I heard about these shaft driven bilge pumps while doing an article about bilge pumps, but could not find one for sale.

I kept hearing about this pump driven from the propeller shaft that ran all the time and would just start pumping if the bilge ever filled with water.

After much searching I found this information-

• The system works well but the kits built did not meet OSHA requirements for a lack of a threaded outlet or cam-lock outlet. The company in Sweden went belly up for this reason.
  
• The guy with the patent got his product back and built a heap of pumps that fit OSHA, but then got sidetracked and did not market them.
  
• It took a lot of searching to find the guy with the new style pump.
  
• After finding him and talking he is willing to keep selling his kits

I built a webpage that shows the pump here -

I have a pump on the way to us in Tonga and we'll take a better look at it.

The volume claimed is just amazing. Like 25,000 gallons peer hour. That is about eight 55 gallon drums per MINUTE. They claim they use this same pump hydraulically driven to pump mud for the oil industry. The marine market was just a side line. Can this be real? Can't wait to get my pump. Should be here in a couple weeks.

Augusta- Thank you for the response.

I have run a search for "propeller shaft bilge pump" and I don't get any responses except for the ESP, that is now out of business.
What I really want to know is if this pump is as great as it seems to be then why are they not taking over the market place? If the last company went bankrupt then I want to do a bit of due-diligence.

If the pump is good, and if I honestly feel it is a benefit to the boating community then I don't see anything wrong with making a web page that helps link other boaters to the product.

I have been on sinking boats and it's a bummer. Just one blown through hull is enough to sober up most people. When such an event happens I would love to be able to motor toward a safe port pumping 25,000 gal per hour.

That sounds great to me.

Thanks

Scott
