Alternator Options

We offer a selection of different alternator options (subject to additional cost) to suit most requirements for heat exchanger engine use. However, if you require an alternative solution with specific alternators we can usually design, manufacture and fit suitable alternator supports and pulley drives to suit your needs. Find out more…

Note: Minimum recommended battery: Not included.

Custom Engine Mounts

Beta Marine engines have been fitted into tens of thousands of vessels around the world using our standard engine feet. However engine bearers can vary immensely so when a problem arises, our solution is to offer our unique service of designing and manufacturing engine mounts to suit your individual engine bearers.

Having designed, manufactured and supplied thousands of bespoke engine mounts when required, the additional cost of this option is heavily repaid when your new engine just drops onto your existing engine bearers and lines up with your propeller shaft reducing installation complexity, time and labour.
