Abstract
An outboard motor and improved torsional vibration damper adapted to be supported on the lower end of the output shaft of the engine of the outboard motor. The torsional vibration damper is formed with an oil receiving groove in which oil and fuel which may drain from the engine can collect without affecting the elastomeric sleeve. A drain hole permits the oil to be relieved from the oil collecting groove and this drain hole is threaded so as to receive a puller for pulling the torsional damper from the engine output shaft.
