The starter is a complete, ready-to-install unit measuring 9 x 4.75 x 4.75 inches, sized to bolt directly into the original mounting location without modification.

This starter is built to fit Evinrude/Johnson 2-cylinder outboards, including 50 HP (1972), 55 HP (1978), and 60 HP (1985) powerheads. Sierra manufactures this starter to meet or exceed the specifications of the original equipment part it replaces, making it a reliable choice for boat owners replacing a worn, weak, or failed starter motor.
