The right spare part keeps a good pump in service for decades. This collection covers genuine spares and service kits for the marine pumps we sell - including Jabsco and Whale - with impellers, diaphragms, valve kits, seals and complete service kits for freshwater pumps, bilge pumps, shower drain pumps and toilet pumps.
A pump rarely fails all at once: falling pressure, noisy running or reduced flow usually mean a worn impeller, tired diaphragm or perished valves, all cheap to replace. To find the right kit, identify your pump's model number - it's usually printed on the pump body - and match it to the service kit listed. Carrying a spare impeller and service kit on board is cheap insurance for any cruising boat.
Frequently asked questions
How do I identify which pump spares I need?
Find the model number printed on the pump body or in your boat's documentation, then match it to the corresponding service kit or spare part. If the label is missing, a photo of the pump usually lets us identify it.
How often should a water pump impeller be changed?
Engine cooling and pump impellers should be inspected annually and replaced at the first sign of cracked, missing or set vanes - many owners simply replace them every season as preventive maintenance.
Why has my pressurised water pump started cycling on and off?
Short cycling usually indicates a small leak, a worn pressure switch or a failing accumulator - a service kit or accumulator tank normally cures it.
