Product Description
This 2005 Yamaha 90 HP 2-Stroke Outboard Motor is a proven and dependable Yamaha inline 3-cylinder outboard designed for boaters who want strong performance, straightforward maintenance, and the durability of a classic Yamaha two-stroke.
This engine has approximately 400 hours and has been well maintained, with all systems reported to be functioning properly. For a 2005 model, 400 hours represents a reasonable operating history and makes this a practical option for a replacement motor or boat repower.
The Yamaha 90 HP 2-stroke platform is well known for its simple mechanical design, strong acceleration, relatively light weight, and dependable performance. The 1,140 cc inline-3 engine produces 90 HP and uses Yamaha's oil-injection system, eliminating the need for manual fuel/oil premixing when operated according to the manufacturer's requirements.
With a 20-inch shaft, this outboard is suited to many boats designed for a standard 20" transom. The engine is also an excellent choice for boat owners looking for a reliable 90 HP replacement without moving to the added complexity and weight of a four-stroke engine.
