Background
Tohatsu outboard motors are marine propulsion engines made by Tohatsu Corporation. Tohatsu sells portable, midrange, high-power, and commercial outboards, and the brand is especially common on small and portable outboard applications.
Identification
Identify a Tohatsu outboard motor by the brand name on the engine cowling and the model or serial number plate on the transom bracket, swivel bracket, or clamp bracket.
Tohatsu outboards are identified by a model code, horsepower rating, and serial number on the mounting bracket or engine label. Older Nissan-branded outboards may share Tohatsu service families.
