📖 Model Background

The Yamaha 70 HP F70A—Yamaha’s first 70‑hp four‑stroke—launched around 2009–2010 as a groundbreaking mid-range outboard, introducing a lightweight SOHC 996 cc 16-valve inline‑4 EFI engine. It set new standards by weighing just ~119 kg (262 lb), making it lighter than many two‑stroke equivalents and earning praise for its impressive power‑to‑weight ratio. The F70A also featured a precise single‑throttle‑valve intake, multi‑point EFI, high 2.33:1 gear ratio, and advanced vapor‑management fuel system—resulting in clean emissions, responsive throttle control, and outstanding acceleration. Lauded for its utility on inflatables, runabouts, and cabin cruisers, it remains a top choice for lightweight boats seeking efficient, smooth performance.
