DasMarine 2000 GPH 12v Boat Marine Plumbing Electric Bilge Pump 1 1/8"(29MM) outlet 8.5AMP

Straight out of the box, I put the pump in a 5 gal bucket that was 1-2 inches shy of the top filled with water (plus the pump) so less than 5 gallons. I started the pump against a 24" head and it took 29 seconds to start sucking air so still 3/4" of water in the bottom. I'll estimate conservatively for the manufacturer at 10 gallons/minute or 600 GPH. Pumping downhill onto the ground shaved a second off the time. Nowhere near 2000 GPH and less than the pump I was going to replace. I will be returning. The price was right and maybe it is a good 600 GPH pump if that is what you want.

I love this product I am tempted to buy a second one great great value for the price works amazing on my sluice for gold prospecting

Good price but concerned about a squeaky noise when operating.Re-installed 3 times to eliminate any installation error but none found and still squeaking during operation although seems to be working efficiently.Time will tell.

Quality pump with good output. I use this on a gold washing highbank unit for sifting out river rock down to 1/4 inch. It uses less amp that 3700gph and need more than the 1100gph pumps

Price is great looks the same as a Rule. If it holes up this is a real deal

It's a good pump. Easy to install. Very bare bones / basic pump. Little large for being 2000gph.

This item sucks (pumps) all the water out of my boat.. Great value easy to install. Would recommend to others

Works great.
