Shaft motor

A shaft motor is an outboard motor , which in a boat in an inboard located Bünn instead is installed him at the stern of the boat to the mirror to hang. If the shaft is sufficiently dimensioned, the motor can be lowered into the water using a lowering mechanism.

Advantages over other drives

Outboards can only be attached to hull shapes with a transom , with cutter-shaped hulls only the option of a built-in motor or the mounting of the outboard in a bunker remains.

Heavy outboards that are attached to the transom of a boat also shift the center of gravity significantly to the rear and can therefore impair the sailing properties of sailboats. This can be avoided with an engine bay because the engine is closer to the center of gravity of the boat's construction.
