The new engine has a rating of 169kW (230bhp) @ 2600rpm and is coupled to a PRM 1000D 1.5.1 gearbox. Both engine and gearbox were supplied by Mermaid Marine.

“The new engine was fairly easy to fit with only some slight modifications needed to the width of the engine beds and the pre-filter wiring was quickly made by our electrician,” explained Andrew Wray of the Keswick Launch Company.
