The Buckshot Racing #77 Carter Rotary Vane Fuel Pump is a heavy-duty electric fuel pump originally developed for military and industrial applications. Over time, this rugged rotary vane design has proven extremely reliable in performance boating and racing outboards, operating consistently on pump gasoline, race fuel, leaded, or unleaded fuel.
 
For owners of carbureted two-stroke outboards, this pump provides a dependable upgrade when replacing the factory crankcase-driven mechanical fuel pump or older electric pumps that struggle to maintain steady fuel delivery.
 
Ideal Fuel Pump for Carbureted Mercury, Yamaha, and OMC Outboards
The Buckshot Racing Carter pump is a universal solution for carbureted marine engines, delivering the pressure and flow required by many high-performance V6 and V8 two-stroke outboards from Mercury Marine, Mariner, Yamaha, and OMC.
 
Unlike high-pressure EFI fuel pumps, which are designed for fuel injection systems, this rotary vane pump is engineered specifically for carburetor fuel systems. EFI pumps often produce excessive pressure and can aerate fuel in carbureted systems. The Carter pump maintains stable fuel pressure and smooth fuel delivery, ensuring reliable performance during acceleration and sustained high RPM.
 
Proven Rotary Vane Pump Design
At the heart of the pump is a rotary vane mechanism that provides smooth and continuous fuel flow. This design offers strong priming capability and fuel lift, helping deliver fuel reliably even when the fuel tank sits lower in the hull.
 
The 12-volt wet motor produces operating pressure between 4 and 8 PSI with fuel flow of approximately 50 gallons per hour, and up to 72 gallons per hour at free flow. This range closely matches the requirements of many high-performance carbureted V6 two-stroke outboards.
 
While not flashy in appearance, the Carter rotary vane pump has earned a reputation among performance boaters for its durability and long service life, often outperforming popular aftermarket pumps such as Holley Red and Holley Blue in carbureted marine applications.
 
Complete Installation Package
The Buckshot Racing #77 Carter fuel pump includes components needed for straightforward installation. Each pump is supplied with 3/8-inch brass hose barb fittings, a bulkhead mounting bracket, and power wire leads.
 
The pump installs externally in-line within the boat’s fuel system and uses 1/4-inch NPT threaded inlet and outlet ports.
