More info

The new and exclusive VS SPEED M04 super long stroke .21 marine engine is based on the very powerful VSR04 on-road engine and is an extraction of the world famous OS Max precision and technology together with some additonal 'Rody' touch and development, equipped with a VS Spec water cooled head. 

The V.S. SPEED M04 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. 

Inside the V.S. SPEED M04 you will find:

  • A 3-Port shaped exhaust which opens at 270° and closes at 90°, total open 180° 
  • A 7-port intake opens at 300° and closes at 60°, total open 120°
  • A new Bi-Turbo, 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!
