Jabsco 29470-2531 Bronze Flange Pump 020 BSP
If you're dealing with a tired or leaking raw water pump on a small marine engine, the Jabsco 29470-2531 is a solid replacement worth considering. This is a bronze-bodied, flange-mounted cooling pump built on Jabsco's compact 020 platform, fitted with 3/8" BSP threaded ports for easy hose or fitting connections. The bronze housing stands up well to saltwater exposure, so it doesn't corrode or seize the way lower-grade materials can after a season or two in a marine environment.
What makes this pump practical for boat owners and technicians alike is its self-priming design. It draws water into the system on its own during startup, without needing to be manually primed first, which simplifies both installation and everyday operation. The flexible impeller inside moves water efficiently at low to moderate engine speeds, keeping your engine's cooling circuit running smoothly whether you're idling in a marina or cruising offshore.
Because it's a direct-fit style replacement pump within the Jabsco 020 size range, it's commonly used to service or upgrade cooling systems on smaller marine diesel and petrol engines. Installers appreciate that the flange mount and BSP port configuration match many existing OEM setups, which cuts down on extra adapters or modifications during a swap.
