6EY‑81940‑00‑00 Starter Relay Assembly—superseded by 6EY‑81940‑09‑00—keeps your Yamaha outboard turning over every time. The compact 4‑pin unit arrives in an epoxy‑sealed housing with a stainless mounting tab that lines up perfectly on F150, F175, and select V6 blocks. An OEM‑style harness connector snaps straight into factory wiring, while silver‑alloy contacts deliver full cranking amperage without arcing, guarding your ignition system from voltage drop.

Why upgrade to the latest relay?

• Plug‑and‑play fit—no splicing or adapter leads

• Salt‑spray‑proof shell and weather‑tight grommets endure harsh marine environments

• Built‑in 30‑amp blade fuse offers quick, tool‑free protection

Swap this relay in before the original fatigues, and you’ll spend less time bumping the key and more time chasing the horizon. At barely three ounces, it nests beside the ECM without crowding cables, and installation takes minutes with a 10 mm socket. Reliable starts preserve battery life, protect the starter motor, and keep weekend runs smooth from the first dawn launch to the twilight tie‑up.
