Stuart 6A compound marine engine - stock code 10902

A quantity of the larger castings for a Stuart 6A compound launch engine - the largest engine in their range rated at 4bhp at 120psi - along with a couple of sheets of drawings.

Includes:

  • Cylinder block, bored and faced
  • Top LP cylinder cover unmachined, bottom machined
  • Valve chests and covers machined
  • Bed plate machined
  • Rear standards unmachined
  • Front standard rods machined
  • Connecting rods part-machined

Still a way way to go, but several of the larger, more expensive castings present and already done - much of the rest could, if required, be machined from stock material.

Castings and drawings are still available from Stuart, there is more information about the engine on their website here.
