Marine propulsion unit having a rotating cylinder driving an impeller

A method of driving an impeller of a marine propulsion unit system, comprising the steps of:

• providing a vessel;
• providing said marine propulsion unit connected to said vessel, said marine propulsion unit comprising, a cylinder, said cylinder substantially surrounding an impeller, said impeller connected to said cylinder, said cylinder having a first end located opposite a second end, said cylinder having a first bearing member and a first sealing member located on said first end of said cylinder, said cylinder having a second bearing member and a second sealing member located on said second end of said cylinder, said cylinder having a plurality of magnets connected to said cylinder, said plurality of magnets are located between said first bearing member and said second bearing member, and said cylinder is substantially surrounded by a housing, said housing connected to at least one coil winding, said housing has a reduced diameter inlet and outlet, bulging out towards a centerline to contain said at least one coil winding;
• providing an electrical power source associated with said at least one coil winding, whereby, the combination of said at least one coil winding and said plurality of magnets form a motor causing said cylinder to rotate within said housing when said electrical power source is applied to said at least one coil winding;
• providing an electronic speed control, said electronic speed control is electrically connected with said at least one coil winding, said electronic speed control receiving commands from a switch;
• producing thrust in first direction when a liquid is drawn into said first end of said cylinder, whereby, orienting said vessel in a first orientation;
• and,
• producing thrust in a second direction when said liquid is draw into said second end of said cylinder, whereby, orienting said vessel in a second orientation.
