A marine propulsion unit, for mounting on the transom of a boat, has a horizontally oriented input shaft and is angularly tiltable in the vertical plane about a point forward of the point of attachment to the transom during operation. The configuration enables the location of the driveshaft housing and lower unit at a point further aft of the transom to keep the marine propulsion unit's center of gravity in a more aftward position, enabling an extended length exhaust system, better control and handling of the exhaust, increased torque, and an increasing overall engine efficiency. The low profile of the marine propulsion unit coupled with its far forward pivot point requires a smaller motor well space and increased visibility in the direction aft of the boat.
