The new and exclusive V.S. SPEED 2010M super long stroke .21 marine engine is based on the very powerful O.S. Speed R2101 engine and is an extraction of the world famous OS Max precision and technology together with some additional 'Rody' touch and development, equipped with a V.S. Spec water cooled head.
The V.S. SPEED 2101M 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 "EXPERIENCED" users.
