<h3>About Jabsco</h3><p>Few names carry as much weight in marine fluid handling as <strong>Jabsco</strong>. Founded in the 1930s in California, Jabsco revolutionized fluid handling by creating the first self-priming flexible-impeller pump — a design that set the standard for reliable pumping across marine, industrial, and sanitary applications. Now part of Xylem, Jabsco leads in marine and industrial pumps, toilets, washdown systems, and searchlights, still known for rugged, reliable gear built on its iconic impeller design.</p><p>Jabsco&apos;s flexible impeller design ensures self-priming, smooth flow, and reliable performance — ideal for demanding marine, industrial, and sanitary applications. Whether you&apos;re outfitting a weekend cruiser or a serious offshore vessel, Jabsco&apos;s engineering pedigree means you can count on every component to perform when conditions get tough.</p><h3>Marine Sanitation Done Right</h3><p>When it comes to onboard plumbing, Jabsco is the gold standard. As the world&apos;s leading manufacturer of small-craft marine toilets, Jabsco provides exceptional quality and value in onboard sanitation. Their lineup covers everything from time-tested manual models to fully electric systems. The Jabsco manual toilet is the world&apos;s best seller: clean to use, with a china bowl that won&apos;t scratch or discolour, designed for ease of service in restricted spaces.</p><p>For boaters who prefer a more hands-off approach, Jabsco electric marine toilets feature dual-function pumps that eliminate messing around with hand pumps and dry bowl valves — a push-button flush rinses the bowl while a high-capacity macerator and scavenger pump grind up waste and pump it out. The full range of <a href="/11525-jabsco-toilets-manual-electric-fixed-mount-parts-201081">Jabsco marine toilets, manual &amp; electric models, and replacement parts</a> makes it easy to find the right solution for any vessel and budget.</p><h3>Effortless Engine Oil Changes Onboard</h3><p>Changing engine oil on a boat can be one of the messiest jobs in marine maintenance — but Jabsco makes it straightforward. The Jabsco DIY Oil Change System provides a clean, efficient, and mess-free solution for changing engine oil in boats, RVs, generators, and inboard engines. The pump used in Jabsco&apos;s multi-engine oil change system is powerful enough to change oil in a typical V-8 engine in just minutes.</p><p>For permanent installations, the pump is designed to be installed near a vessel&apos;s engine and permanently plumbed to the engine&apos;s oil pan, and with the integral reversing switch, the flow direction can be changed to pump a measured amount of new oil back into the engine.
