A radially soft drive coupling for reducing vibration transmitted across the coupling in certain marine drive applications. Elastomeric elements (54, 56) are bonded to the hub (22) and in frictional engagement with the housing (42). The elastomeric elements (54, 56), interconnecting the hub (22) and housing (42) are precompressed by an amount which is at least in the range of 15-20 % to produce significant radial and torsional softening of the spring rate of the elastomer. The radial spring rate whose magnitude expressed in lb/in is in the range of between one half and three times the magnitude of said design torque level expressed in 1b-in. Frictional engagement of the elastomeric elements (54, 56) with the housing (42) slips when a design torque is exceeded.
