The standard propeller extension is 1.5" but up to a 4.75" can be used. With a 12" spinner, only a small drop to the cowling at the front is needed to enclose the engine.

FLYING THE VIKING 90
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.
