Pump Parts & Accessories
Every marine pump eventually needs a part replaced long before the pump itself wears out. This category covers the impellers, pressure switches, and service kits that keep a bilge and water pump running instead of needing a full replacement, whether that pump handles engine raw water cooling, freshwater pressure, waste, or ballast duty.
What to Look for in Pump Parts & Accessories
Fit matters more than almost anything else in this category. An impeller kit has to match the exact blade count, material, diameter, and drive type the original called for, since even a close match can leave a pump running rough or overheating. Material matters too: neoprene impellers suit most raw water and freshwater applications, while nitrile holds up better where the pump sees any exposure to oil or fuel. For pressure switches and service kits, confirm the pump series and model number before ordering rather than assuming a universal fit, since Jabsco and Johnson Pump both run several closely related product families with different internal parts.
What This Category Covers
Impeller kits make up the bulk of this category, spanning a wide range of blade counts, diameters, and drive styles to match specific pump models across Jabsco, Johnson Pump, and other brands. Pressure switches keep freshwater diaphragm pumps cycling on and off correctly as tank pressure rises and falls. Service and rebuild kits bundle the diaphragms, valves, seals, and hardware needed to fully rebuild a worn pump or marine toilet rather than replacing the whole unit, and other replacement parts like aerator heads round out the category for anyone maintaining a livewell or baitwell system.
Complete Your Pump Setup
Once the right part is in hand, pair it with the pump it belongs to. Shop Bilge Pumps for the pumps themselves, Bilge Pump Switches & Accessories for float switches and panel controls, Fresh Water & Washdown Pumps for freshwater pressure and deck wash systems, Livewell & Baitwell Pumps for aeration and bait tank circulation, and Shower Sump Systems for shower drain pumps.
