A thruster system for a marine vessel includes an electric motor having an output shaft. The thruster system also includes a housing having a first housing opening and a second housing opening, the first housing opening defining a water intake, the second housing opening defining a water discharge. The thruster system further includes a rotatable member operatively coupled to, and driven by, the output shaft of the electric motor, wherein rotation of the rotatable member results in water brought into the housing through the first housing opening and expelled through the second housing opening to generate a thrust force in a direction that is greater than 45 degrees relative to a propeller direction of the marine vessel.
