Arco 3426 Replacement Outboard Starter Motor
The Arco 3426 is a direct-fit replacement starter for Yamaha outboards across two distinct application windows — covering both the high-horsepower 2-stroke lineup from the mid-1980s through the mid-1990s, and the 40–50 HP 4-stroke models from the late 1990s. It replaces the original Hitachi unit with a 9-tooth drive gear and drops in without modification, restoring reliable starting performance to engines that have seen years of hard use.

Parts Desk Insights
The 3426 covers two very different Yamaha application windows — confirm both your engine's horsepower and model year before ordering, as the 2-stroke and 4-stroke fitments don't overlap. The 9-tooth drive gear is the key spec to verify against your existing starter before purchasing. This is a popular replacement on older Yamaha 2-stroke V4 and V6 engines that have accumulated significant hours; if the starter is turning slowly rather than failing outright, it's worth inspecting the brushes first — the Arco Starter Motor Brush Kit (BK900) can extend starter life significantly on high-hour engines. For other Yamaha electrical components, also see the Arco Heavy-Duty Tilt/Trim Motor for Yamaha Outboards.
