Complete Rebuild Kit for Whale Gusher 10 Mk2 & Mk3 Manual Bilge Pumps
Keep your Whale Gusher 10 manual bilge pump operating at peak performance with this comprehensive nitrile service kit. Designed for Mk2 and Mk3 pump variants, the kit includes all the wear parts needed for a full pump overhaul — valves, seals, and diaphragm components — so you can restore original pumping efficiency without replacing the entire unit.
Nitrile rubber compounds offer excellent resistance to oils, fuels, and bilge contaminants, making this kit the preferred choice for bilges where fuel or oil contamination is a concern. Servicing your Gusher 10 regularly extends pump life significantly and ensures reliable performance when you need it most.

Parts Desk Insights
Best Use Case: Choose this nitrile kit when your bilge has a history of fuel or oil contamination — nitrile holds up significantly better than neoprene in hydrocarbon environments. For clean-water bilge applications, the Whale Gusher 10 Neoprene Service Kit (AK3706) is an equally capable and slightly lower-cost option. For additional pump components, see the Whale Eyebolt & Clamp Plate Assembly for Gusher 10 and the Whale Gusher 10 Gaiter Kit for Deckplates. If the pump body itself is damaged, consider replacing with the Whale Gusher 10 Manual Bilge Pump with Underdeck Mount or the Whale Gusher 10 Manual Bilge Pump with On Deck / On Bulkhead Mount.
Note: Confirm your pump is a Mk2 or Mk3 variant before ordering — this kit is not compatible with Mk1 or other Gusher models.
