Introducing Viking 90 HP to the world - Rotax 912 replacement for $9,995.00
A lightweight gearbox development is complete for the 90 HP Viking model. This gearbox will work on pusher aircraft and on installations where the propeller does not have to be at the top of the engine. For those installations, a 3 gear gearbox is used.
The port injected engine is more fuel efficient than the carbureted Rotax engine. So, you will do as good or better when planning fuel flow.
