The new and exclusive V.S. SPEED M01-EVO2 super long stroke .21 marine engine is based on the very powerful O.S. Speed R2101 engine and is an extraction of the worldfamous OS Max precision and technology together with some addional 'Rody' touch and development, equipped with a V.S. Spec water cooled head. 

The V.S. SPEED M01-EVO2 is equally suited for a gearbox application in FSR-V/O boats but also direct drive boats such as FSR-H outrigger hydroplanes (especially the latest generation 3-point riggers).
This engine is intended for "EXPIERIENCED" users.

  • A 3-Port shaped exhaust which opens at 270° and closes at 90°, total open 180°

  • A new UltraLongStroke, balanced and DLC treated crankshaft intake opens at 25° and closes at 250°, total open 225°

This combination has proven to give excellent overall performances!
