SHURFLOAqua King Ii 4.0 Fresh Water Pump, 12v

I bought this pump to replace the original belt-driven pump in my boat. The original pump was the same amperage as this one, but this one delivers better pressure to the faucets. It's now a scenario that the pressure flow is restricted by the faucets and shower head, not the pump itself. This pump is also quiet. That said, I do not want a silent pump in my boat. if the pump is cycling due to a leak somewhere, I want to hear it. This makes enough noise for that purpose but it is not noisy enough to be annoying. Mine is installed directly below an interior dinette seat, so it's in the "living area" of the boat. My point being my installation is about as loud as it's going to get and it's satisfactorily quiet. It does draw 10 amps when it runs per my instrument panel. This is fairly high amperage, but by going with this pump, I do not need a separate wash-down pump for the exterior of the boat.

Make sure the pump replaces the same water pressure as what time down. You don’t need any downstream failures due to additional psi.

Well packaged, arived when it was promised, quality product, exact replacement

Arrived on time. This is a perfect replacement for the same model I had in my boat. Easy to install, runs great.

Unusable as outlet port fitting was broken off - $160 fraudulent advertising I’ll be returning for a full refund. Buyer beware.

We live aboard our boat full time. These as well as other brands all use the same pressure switch which fails after a few months. Don’t buy the switch from the pump manufacturer. They’re $3.00 online elsewhere. I changed out to a stand alone pressure switch and solved the problem. Use a LeFoo pressure switch available on Amazon. Other than that it’s a great pump

I bought this as a replacement unit for my previous Shurflo. The original was discontinued model. This is the 3rd fresh water pump I have put on the boat. Seems they only last about 5 years. The only reason I did not rate this 5 stars was because the pressure sensitive shut off was not adjusted properly from the factory. It's easily adjustable using a small allen wrench. If you don't have it automatically shut off, the pump will run endlessly, damaging your pump (over heating), and you'll burn your battery down. Be sure to flush ALL your places where water flows (Sinks, showers), before adjusting the pressure shut off, as air in any line will create a false positive on shut off adjustment.

This pump is very quiet, smooth and powerful. Too bad it only lasted 2 months.Update: actually, it was my bad that the pump stoped working. Had to work out a short circuit. Anyways, this bad lil’ pump has been AMAZING! It’s so quiet and smooth and reliable.
