Banish rough idle and fuel-starved surges with Yamaha’s OEM Injector 6EK-13761-01-00—the exact, flow-matched unit your F115/F130 four-stroke was born with. Housed in a rust-proof stainless body and topped by Yamaha’s signature green EV1 connector, this injector meters fuel to the millisecond, atomizing each pulse through a four-hole, 60-micron tip for crisp throttle response from idle crawl to wide-open run.

Why owners swap in the real thing

• Factory-matched 240 cc/min flow keeps all four cylinders burning evenly—no stumble when you punch it.

• Integrated basket filter traps varnish and micro-debris before they reach the nozzle.

• High-temp Viton O-rings seal tight against ethanol blends and 180 °F rail heat.

• Plug-and-play harness clicks straight into the stock loom—no splices, no “universal” guesswork.

Practical payoff? Cleaner starts, steadier trolling, and that smooth Yamaha mid-range pull you remember from day one. Install during routine service or whenever a scan tool flags a lazy injector; the job takes about 30 minutes and rewards you with seasons of trouble-free runs. One smart swap, a world of difference every time you throttle up and head for open water.
