📖 Model Background

The Yamaha 80 HP 3-cylinder 2-stroke outboard, produced between 1997 and 2001, served as a versatile mid-range option for anglers and small commercial operators. Utilizing the same proven 1,140 cc loop-charged inline-3 platform found in Yamaha’s 85 HP and 90 HP models, it delivered smooth 80 HP performance while offering reduced fuel demand and slightly lighter weight. With CDI ignition, oil-injection, and dry weight in the 120–130 kg range, the 80 HP was popular on skiffs, bay boats, and lightweight fishing vessels where balance and reliability mattered most.

This manual supports all Yamaha 80 HP 2-stroke outboards built during this period, including model variants such as 80BETOX, 80TLR, and other electric-start or remote-control configurations using the same 3-cylinder powerhead. Every key system is covered - from powerhead service to fuel, ignition, and trim/tilt procedures.
