This robust aftermarket flat coil spring serves as a reliable swap‑in component for Tohatsu 4HP, 6HP, 8HP and 9.8HP outboard motors. It cross‑replaces OEM part numbers 3B2‑05010‑1, 3B2050101, 3B2‑05010‑0 and 3B205‑0100M.
It is fabricated from tempered high‑tensile spring steel. This flat coil spring delivers solid wear‑resistance and excellent anti‑fatigue traits. It withstands repeated tension‑release cycles, steady engine vibration and damp, salt‑rich marine environments, so it keeps steady elastic force across long service periods.
Positioned inside the recoil starter housing, this flat coil spring links the starter reel and outer casing. It creates rebound tension to automatically retract the starter rope right after each manual pull. Proper spring tension guarantees fast, smooth rope take‑up for every starting attempt.
