Westerbeke 4.2 MCGB
The 4.2 MCGB is designed for larger petrol powered sports boats which will have some air con, an electric galley and other typical consumers needing a mains supply. Designed to be as compact as possible, the 4.2 MCGB fits easily in the engine room or aft compartment of medium sized power boats. Powered by a 3 cylinder fuel injected petrol engine running at only 1500rpm, the 4.2 MCGB is extremely smooth and quiet.
