Gazelle Auxiliary
The standard engine being fitted is the Simpson S217 (25.5 bhp) mated to a ZF 12M reduction gear.
Of course it is possible to fit any number of other engines - the only significant criteria from a design point is weight - Gazelles must not be weighted down aft - and unless hydraulic props are used the auxiliary is aft.
