Jabsco 18830-0010 Engine Cooling Pump with 6-1/2" A Pulley
Keeping an engine running cool comes down to trusting the pump that moves the water, and the Jabsco 18830-0010 has built that trust across decades of use on the water. Machined from solid bronze with a stainless steel shaft and a carbon/ceramic mechanical seal, this pump is designed to shrug off the harsh, corrosive conditions that come with constant exposure to raw water. The Neoprene flexible impeller at its core is what gives the pump its self-priming ability, letting it pull water from dry up to nearly 8 feet and lift it as high as 22 feet once wetted, so it starts working the moment the engine turns over.
What makes this particular version convenient is that it arrives ready to install, already fitted with a 6-1/2" "A" section belt pulley. That means less time sourcing separate parts and more time getting the engine back on the water. It's a natural fit for anyone replacing a worn Sherwood G-30-2 pump on a Chris-Craft 305, 327, or 350 C.I. engine, and it also lines up with several older Glastron, Pleasurecraft, and early Volvo engine setups.
Beyond the marine world, the same rugged construction and self-priming performance make this pump a solid option anywhere a bronze, belt-driven water pump is needed to circulate liquid reliably and consistently, whether that's a workboat engine room or an industrial cooling loop that calls for a dependable flexible impeller design.

Frequently Asked Questions
Q: Can the Jabsco 18830-0010 run dry during startup?
A: It can briefly self-prime dry, but it should never run without water for more than 30 seconds, since the impeller depends on liquid for lubrication and will be damaged without it.
Q: Does this pump come with a mounting bracket?
A: No, the pump is supplied as a bare pump with the 6-1/2" A pulley attached; a separate mounting bracket is needed to secure it and maintain proper belt tension.
Q: What direction should the pump rotate?
A: The pump can be mounted in any position, but the direction of shaft rotation determines which port serves as intake and which serves as discharge, so this should be checked against the engine's rotation before installation.
Q: Is this pump only for marine use?
A: While it's most commonly used for marine engine cooling, its bronze construction and self-priming design also make it suitable for other belt-driven liquid transfer applications outside of boats.
Q: What temperature range can this pump handle?
A: It's rated for liquids between 45°F and 180°F; pumping colder water can shorten the lifespan of the impeller.
