SIERRA Carburetors 18-7607-1 Carburetor Replacement For Rochester 1782403

When a carburetor on a Crusader 454 cannot be re-built, it’s time to replace it.

For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders to a point of supplying them with OEM parts. Boaters can be assured a Sierra part will fit and restore function.

Each Sierra re-manufactured carburetor meets or exceeds manufacturers’ original specifications. During the re-manufacturing process each carb is re-calibrated for maximum efficiency and performance, mating surfaces are machined to ensure gaskets provide the best possible seal and shaft bushings are replaced to reduce play. A flow test is performed to ensure consistency throughout the throttle range. A base gasket is included to make installation straight forward. After some minor idle and choke adjustments, you will be back on the water.
