📖 Model Background

The Yamaha 100 HP 2-stroke outboard, manufactured between 1997 and 2002, was designed as a dependable option in Yamaha’s mid-range V4 lineup. Featuring a 1,730 cc loop-charged two-stroke engine with oil-injection and CDI ignition, it produced solid 100 HP output with smooth power delivery across the RPM range. Weighing approximately 165 kg (365 lb), it was well-suited for coastal fishing boats, lightweight runabouts, and utility craft needing efficient, no-nonsense propulsion.

This manual supports all 100 HP Yamaha 2-stroke V4 models from this production window, including trim and shaft variants such as 100TXR, 100TLR, and other configurations built on the same 1,730 cc powerhead. Regardless of steering setup or start type, all mechanical systems are covered in full detail.
