Yamaha Oil Pump Assembly – SKU 6EY‑13300‑00‑00

Keep your Yamaha four‑stroke running silky‑smooth with the very pump that feeds its lifeblood. This genuine assembly uses a gear‑driven rotor to deliver a steady oil stream from idle trolling to wide‑open throttle, protecting bearings and cam lobes from heat and friction. The cast‑aluminum housing is anodized inside and out, so salt spray and modern ethanol‑laced fuels don’t stand a chance.

• Factory‑matched flow: precision‑cut steel gears hold pressure at 50 psi on F150/F175/F200 engines
• Corrosion‑smart build: marine‑grade anodizing and stainless hardware fight rust in brackish or offshore waters
• Ready to drop in: pre‑installed Viton O‑ring and keyed drive shaft line up with the crankcase—no shimming, no guesswork
• Leak‑free seal: integrated pressure‑relief valve keeps gaskets intact even during cold‑start surges

Swap this pump during your 500‑hour service and you’ll notice faster pressure rise on startup, quieter valve gear, and longer oil life. Because it’s built to Yamaha’s micrometer tolerances, installation is a 30‑minute job that sends you back to the dock with confidence. Reliable lubrication means fewer worries and more time chasing the horizon.
