Beta Marine was formed in 1987 by four marine engineers who brought to the company a combined total of over 70 years experience in the design, manufacture and marketing of marine diesels. Their objective was to provide propulsion engines and marine generating sets to suit individual requirements rather than to the specification dictated by the larger boat builders.

This special applications expertise rapidly gained the company market share and linked with sensible pricing the company is now a major equipment supplier to the international yacht, work boat, and canal boat markets. Beta has now supplied over 25,000 diesels and with a turnover of £8m and with 38 employees this profitable company continues to grow with satisfied customers acting as excellent ambassadors for the business.



Here at Access Marine, we specialize in repowering both sail and power boats.  We have vast experience with diesel engines installation.  Often times, a repower will require custom fitting to install the engine to the manufacturer’s specifications.  Access Marine closely follows ...



This guide lists some of the more popular, older yachts that have been re-powered, and the engine size used. Choosing an engine size depends upon several different criteria and we would recommend that you discuss with other owners of your class of yacht as well as your local Beta Dealer / Engine Installer. 





You may begin to think about repower when your marine engine begins to show subtle signs of aging, like a longer cranking time at start-up or performance that’s not quite what it was when the boat was new. Sometimes, a more serious problem has developed: a plugged water intake caused the engine to overheat, striking a submerged object caused serious damage, or an unexpected freeze resulted in a cracked block.

Obviously, if the current engine fails during the season you want to get back on the water as quickly as possible. Your options may be limited because during peak season the service bays are busy. You’ll want to limit your choices to what is available and what can be serviced rapidly without loosing valuable boating time.

Ideally, you should consider the decision to repower during the off season before a catastrophic incident. Doing your homework in advance provides you the opportunity to find the right product at the best price, and not lose valuable time on the water.
