Two cylinder, four cycle smoothness in a lightweight, compact engine

The Westerbeke B advanced series engines have an extremely small "envelope" ("envelope" is the combined length, width, height). These light-weight low profile engines are designed to fit into the smallest engine compartments. They are engineered by Westerbeke, pioneers in marine diesel engines, to provide consistent performance, quietness, durability and above all reliability, year after year.

The B series engines are easy to install, economical to operate, and convenient to service. A full range of options is available allowing you to custom tailor your engine to fit your individual requirements.
