Sierra 223-7201 Carburetor Kit for Westerbeke Generators - Replaces 38100

The Sierra 223-7201 is a replacement carburetor kit built for Westerbeke marine generators. It is engineered to meet or exceed the performance of the original equipment carburetor it replaces, using marine grade materials to withstand the harsh onboard environment. The kit is designed as a direct equivalent to Westerbeke part number 38100 and OEM part number 723359, giving boat owners a straightforward way to restore proper carburetor function without sourcing a full new assembly.

This carburetor kit is intended for owners performing generator maintenance or rebuilding a worn or malfunctioning carburetor on a compatible Westerbeke generator set. The unit has a machined exterior finish and ships as a single count item measuring 7 inches by 6 inches by 1 inch. At 0.17 pounds, it is a compact, lightweight kit suited to routine service work in the engine room or generator compartment.

Fitment covers a range of Westerbeke BEG and BCG generator models across their 50Hz and 60Hz output ratings, so it is important to confirm the generator model designation before ordering. Sierra backs the part with its standard customer satisfaction warranty covering defects in materials and workmanship.
