With a slightly oversized engine to power ratio, the 10.3 is popular with commercial and military operators who prefer this for power packages which may endure an unrelenting demand for power day after day. Westerbeke reliability and durability come as standard with this slow running generator. While very quiet running, the sound output can be reduced further with the optional SST-Sound Guard.

Westerbeke Power


Quiet, Compact and Reliable

Designed exclusively for marine applications, Westerbeke slow running diesel generators represent a breakthrough in compactness, quietness, and reliability that has become the industry benchmark and the preferred choice of the most prestigious boat and yacht builders.

Easy operation

Advance Yacht supplies both digital and analogue models with the start/stop panel mounted on the generator. We supply the main panel with a harness so that it can be mounted in a convenient location for easy operation.


Long Life & Easy Maintenance

The engine operates at a low 1500rpm and is fresh water cooled via a heat exchanger for durability in the marine environment. Easy access to most servicing points and individually removable top and side panels of the optional sound enclosure make for easy maintenance.

Peace Of Mind

Westerbeke's diesel generator performance is matched by their extensive global customer service network. Westerbeke work hard to make sure you are taken care wherever you are in the world, whether you need parts, warranty support or technical service.

Classic Analogue

The Westerbeke range of analogue diesel marine generators is designed for leisure and commercial applications where a simpler ‘classic’ control system is preferred.


SST Sound Shield

Engineered for silent operation and ease of servicing, the addition of a stylish and rugged SST Sound Shield reduces the average sound intensity of your Westerbeke up to 50%. Each of the 5 powder coated aluminium panels can be removed with a quick snap of 2 latches so you have full access to all four sides for ease of servicing.



5 year limited warranty for leisure users*
