An outboard marine drive includes a propulsor configured to generate a thrust force in water, and a monolithic supporting frame which supports the outboard marine drive relative to the marine vessel. The monolithic supporting frame includes a body, a support leg extending downwardly from the body and configured to support a propulsor housing for the propulsor, and a steering arm extending forwardly from the body for steering of the outboard marine drive. A power entry module coupled to the monolithic supporting frame, the power entry module being configured to regulate/control current and voltage for powering the propulsor. A service tray is removably coupled to the top of the monolithic supporting frame, the service tray supporting at least one serviceable component of the outboard marine drive.
