ABSTRACT:
An outboard motor is configured for steering by a tiller arm. The tiller arm is moveable relative to the outboard motor about a transverse axis and is arranged to steer the motor about the vertical axis. The outboard motor further has a power head that contains a vibration engine and is comprised of a protective cowling and lower tray. A tiller arm mounting bracket is secured to the power head and a mounting structure extends from the tiller arm. A resilient member is juxtaposed between the mounting bracket and the mounting structure. A gap is defined between a face of the resilient member and the tiller arm such that the resilient member may freely vibrate within the gap without that face of resilient member contacting the tiller and directly translating vibrational energy to the tiller arm.
