Our Purpose

Taking your boat to the next level

Swaymar Marine are dedicated to giving the discerning pleasure power boat owner the type of engines they should always have had. Not the basic, low efficiency, fuel wasting truck/crate engines commonly available. But high output, super efficient, totally reliable engines, specifically designed, built and dedicated to the unique requirements demanded of a high performance marine engine. To this end our technical team have between them over 80 years experience in design and development technology.

The Situation

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.

Our Approach

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.
