Marine propulsion device adapted for a sailboat

A marine propulsion device comprising a power head including a bottom face having therein an exhaust gas passage port, a lower unit connected to said bottom face and including a side surface, a propeller shaft, a propeller carried on said propeller shaft, and an exhaust gas passage communicating with said power head port and terminating in a port in said side surface, and an exhaust gas passage conduit connected to said lower unit for pivotal movement relative thereto and in communication with said port in said side surface and extending upwardly therefrom to above said power head and downwardly therefrom and being adapted to be connected to a duct discharging the exhaust gas into the atmosphere.

A marine propulsion device comprising an engine including a cooling jacket, a lower unit supporting said engine and including a substantially closed cavity including a gear box portion and a sleeve portion and a water jacket cavity surrounding said sleeve portion, water inlet means communicating with said water jacket cavity, a propeller shaft mounted for rotation in said gear box portion of said substantially closed cavity, a propeller carried by said propeller shaft, a drive shaft connected to said engine and extending into said sleeve portion of said substantially closed cavity, gear means in said gear box portion of said substantially closed cavity and connecting said drive shaft to said propeller shaft, and a water pump supported within said lower unit and communicating with said cooling jacket and with said water jacket cavity for delivering water from said water jacket cavity to said cooling jacket.

A marine propulsion device comprising a power head including a bottom face having therein an exhaust gas passage port, a lower unit connected to said bottom face and including a side surface which is intended to extend generally vertically when the marine propulsion device is boat mounted, a propeller shaft, a propeller carried on said propeller shaft, and an exhaust gas passage communicating with said power head port and terminating in a port in said side surface, and an exhaust gas passage conduit connected to said side surface in communication with said port and adapted to be connected to a duct discharging the exhaust gas into the atmosphere, whereby variation in the angular relationship of said conduit to said power head in a generally vertical plane is permitted by the connection of said conduit to said side surface.
