More info

The new and exclusive V.S. Powerhead .21 marine engine is based on the very powerful O.S. Speed 21ZX-R on-road racing engine and is an extraction of the worldfamous OS Max precision and technology together with an addional 'Rody' touch and development

This engine features:

  • Reliable O.S. SPEED quality, power & spare parts availability.
  • A specific 'Rody' shaped crankshaft with left threaded thread so the flywheel will not unscrew itself.
  • PTO Air cooled cooling-head for easier setting of the carburetor and more stable temperatures.
  • A specific 'Rody' 7-Port liner with MES exhaust system
  • Combustion chamber for conical(turbo) glowplugs.
  • Carburetor NOT included so you are free to choose the carburetor of your liking, as long as it has a neck of 15mm.

We suggest to use with this engine maximum 25% nitro fuel.
We have obtained great performances with this VSPTO engine in combination with our self developped exhaust system(Part#HIP2034-OBL), together with the OSmax carburetor(Part#23882000).
