Abstract

A marine propulsion device for use with a boat including a transom. The device comprises a transom bracket adapted to be fixedly connected to the transom, a swivel bracket pivotally connected to the transom bracket for vertical swinging movement about a horizontal tilt axis, and a kingpin having upper and lower ends fixed to the swivel bracket and a central portion intermediate the ends. The device also includes a propulsion unit including a powerhead, a driveshaft housing including an upper surface fixedly connected to the powerhead, a lower surface, and a vertical bore receiving the central portion of the kingpin to facilitate horizontal swinging movement on the driveshaft housing relative to the swivel bracket. The propulsion unit also includes a gearcase fixedly connected to the lower surface of the driveshaft housing, and a propeller rotatably carried by the gearcase.
