An outboard engine system includes: an engine; a casing to which the engine is removably mounted at an upper portion; a torque converter; a vertically arranged output shaft connected to a crankshaft via the torque converter; a horizontally arranged propeller shaft provided below the output shaft; and a forward-reverse shifting gear mechanism for providing a connection between the output shaft and the propeller shaft. The casing includes: casing main sections for housing the output shaft, the propeller shaft, and the forward-reverse shifting gear mechanism; and distance members removably jointed to the upper end of the casing main sections so as to house the torque converter. Both the casing main sections and the distance members are configured to be able to removably mount the engine. Thus, the casing having the main sections can be used in both an outboard engine system with a torque converter and an outboard engine system without a torque converter.
