Hose size: 3/4". No tools needed for maintenance, no need for complete disassembly. You can now leave the pump casing attached to both the boat and the hoses. Pump body: Thermoplastic. Amperage: 3.2 A.
These pumps are manufactured under a variety of name brands using identical materials, design, and construction. Although self-priming, they have consistently failed to pump bilge water out of my boat after about one season's use. I routinely clean my bilge and the pump to ensure nothing is blocking the intake or discharge but what I've found is that the release tab on the pump body breaks easily, and that regardless of how well I clean it or the bilge, the pump short-cycles very almost constantly. That is, it will pump the water into the discharge hose until the water level in the bilge drops below the mirus field detector level (the black square that serves as part of the "combo"), but then the water remaining in the discharge line will flow back down into the bilge and re-trigger the field detector, thus setting off the pump again. Johnson Pump includes a duck-bill valve that you can insert into the discharge hose to help prevent this, but it is an ABYC violation to do so, and thus far has not improved pump efficiency or performance in my boat. Total head pressure in my aft bilge discharge is less than four feet, and I have incorporated smooth bore hose of the proper diameter with no kinks or sharp bends. Also problematic is the mirus field detector unit, which seems to detect elevated water levels even when the pump is doing it's job. You can mitigate this by keeping the detector clean. Overall, it's a huge pain to deal with. I'm on my fourth season with a new tug boat and have replaced the aft bilge pump six times. I regularly come aboard to find it running despite little to no water in my bilge and presume it had been running all night. Overall, an expensive and poorly built product. Looking now for another solution that will fit in my narrow bilge.
