Abstract: A marine drive which mounts through a hole in the bottom surface of a boat utilizes a driveshaft housing assembly, an engine mounted to the driveshaft assembly and a lower propeller drive unit mounted to the driveshaft housing assembly. The driveshaft housing assembly which mounts the drive within the hole in the boat includes a driveshaft housing, a steering assembly constructed to rotate about a generally vertical axis within said driveshaft housing assembly to provide steering, a trimming assembly connected to the steering assembly to pivotably swing the lower propeller drive unit to provide trimming/tilting, a driveshaft and an exhaust passageway therethrough.

Abstract: A propeller drive for a boat which provides independent steering and independent trimming/tilting mounts through a hole in a bottom surface of the boat. Steering of the propeller drive is provided by a steering assembly constructed to rotate about a generally vertical axis for connecting the drive up through the hole in the boat. Trimming of the propeller drive is provided by a trimming assembly which is pivotally connected to swing the propeller drive generally horizontally from the steering assembly.
