ABSTRACT:
Disclosed herein is vibration isolating arrangement for an outboard motor having a propulsion unit mounted rearwardly of the steering axis of the outboard motor and including a powerhead, a drive shaft housing having a drive shaft, and a lower unit carrying a propeller. The mounting arrangement includes an upper mount and a pair of lower mounts secured to the propulsion unit in vertically spaced relation and rearwardly of or behind the drive shaft. The top mount includes a cross bar which has a wedged-shaped cross section with the upper and lower surfaces thereof converging in the direction of propeller thrust, which is supported by a resilient bushing within a casing, and which has outer ends extending from the casing transversely to the direction of propeller thrust for connection to a swivel bracket. The lower mounts are mounted in laterally spaced recesses provided in the drive shaft housing. Each of the lower mounting units includes an insert which has a wedge-shaped cross section with the upper and lower surfaces thereof diverging in the direction of forward propeller thrust and which is supported by a pair of resilient pads disposed between a pair of spacer members which fit snugly into opposed grooves provided in each drive shaft housing recess.
