The present invention provides for a reagent vaporization system. The reagent vaporization system includes a vaporization chamber located within a stream of hot exhaust gas. An aqueous reagent source located outside of the stream of hot exhaust gas provides aqueous reagent to the vaporization chamber. The heat from the hot exhaust gas vaporizes the aqueous reagent, which is then introduced into the stream of hot exhaust gas.

A marine propulsion system is provided with a hydrophobic membrane disposed across a port of its cooling system which allows air to pass through the membrane, but inhibits water from passing through it. During draining procedures, air can freely pass into the cooling system through the membrane to replace evacuated water and avoid the formation of low pressure regions within the cooling system. During initiation of the marine propulsion engine, following a period when what has been drained from the cooling system, air can freely pass through the membrane to be expelled from the cooling system as it is replaced by water pumped in the cooling system by a sea pump.

A drive assembly coupler to transfer torque from a motor shaft. The coupler includes a body having a first end, a second opposed end, and an axial opening through the body extending between the ends. A first pair of opposed channels is provided in the body, each channel parallel to the other and parallel to the opening. A second pair of opposed channels is provided in the body, each channel parallel to the other and parallel to the opening. A first U-shaped insert has a threaded opening receivable in the first end and has a first pair of extending legs receivable in the first channels. A second U-shaped insert has a threaded opening receivable in the second end and has a second pair of extending legs receivable in the second channels.
