Abstract
A propulsion unit arranged to propel a waterborne vessel comprising an electric motor arranged to provide propulsion, and a housing arranged to contain the motor. The motor is mounted within the housing on resilient couplings. Such propulsion units are used to propel ships, and the like, and are suspended from beneath the vessel. The resilient couplings reduce the noise emitted by the housing.
