To this end our technical team have between them over 80 years experience in design and development technology.
An engine failure in a boat can be life threatening. Due to the fact that reliability is paramount in a boats engine, marine engines are commonly based on low specification truck variants. This assumes that by imposing less stress on the components, the engines will be more reliable, and is correct when applied to the limitations of the standard components.
To provide top quality performance engines with improved reliability and economy to the UK boating industry. As a result of careful and thorough research, drawing on over 40 year's engine building experience - in conjunction with our consultant and world authority David Vizard - Swaymar Marine have designed a unique, far superior product specifically optimised for marine applications.
