We tested several high output models of both the Attwood and Rule Bilge Pumps. A Rule bilge pump can be found in many new boat bilges. For our test of bilge pumps rated over 1400 GPH we pitted three Rule pumps against a pair of high-capacity Attwood pumps. Our five

Bilge Pumps
Marine Bilge Pumps Rated 700 to 1250 GPH
We fully tested and reviewed seven electric bilge pumps from three different makers in the 700 to 1250 GPH size range. We tested the Attwood V750, V900, and V1250, from Rule the 800, model 20R, and the 1100, model 27D, with two Shurflo Piranha pumps, the 700 and 1000, filling
Marine Bilge Pumps Rated Under 400 GPH
Bilge pumps from three makers, Rule, Whale, and Shurflo each have a pump fitting this flow category; all are rated at less than 400 GPH. Both the Shurflo Piranha 380 and Rule 360, model 24 have vertically orientated motors and snap-on bases designed to mount on a horizontal surface. The
How We Test Electric Bilge Pumps
We gathered actual flow rates and power ratings on all the bilge pumps at two voltages while pumping water into a tank set five feet above the pump using saltwater. Each pump was mounted to our test bench and connected to a fuse panel using the factory wire leads. The
Marine Bilge Pumps Rated 500 to 625 GPH
Bilge Pumps from several makers fit this group. We tested a Shurflo Piranha 500, a pair of Attwood’s the V500 and V625, a Rule 500 model 25D, and a Whale SuperSub 500 model SS5012. Rule and Shurflo all have vertically orientated motors and snap-on bases designed to mount on a
Bilge Pumps Main Page
Our 25′ Contender test boat came from the factory with only one bilge pump. And even though a bilge pump is not marine electronics per se it is still an extremely important piece of marine electrical gear that we cover in our reports. After much research we determined this single
Automatic Bilge Pumps
An automatic bilge pump combines a bilge switch and bilge pump motor in the same housing. We ran a pair of these units through our testing. We tested the Attwood Sahara 1100 and the Lovett 1200. Size and construction of these two units is quite different. The Lovett is by
