Yamaha Oil Pump Assembly – SKU 6S5‑13300‑22‑00

Healthy oil pressure is the heartbeat of your Yamaha V‑6, and this OEM pump keeps it rock‑steady from slow trolling to full‑throttle runs. Yamaha machines the housing from lightweight cast aluminum, then anodizes every surface for salt‑water toughness. Inside, a high‑capacity steel gear set spins on needle bearings, pushing out a steady 55 psi so cams, bearings, and chains stay bathed in fresh lubricant.

• Constant, balanced flow: precision‑cut gears deliver uniform pressure at every rpm
• Marine‑grade durability: hard‑anodized body and stainless fasteners shrug off corrosion and stray water intrusion
• Built‑in safeguards: pressure‑relief valve vents surges on cold starts, protecting gaskets and seals
• Ready to install: keyed shaft, alignment dowel, and pre‑fitted Viton O‑ring mean a direct swap in F225, F250, and F300 powerheads—no shimming or sealant required

Drop this pump in during your 500‑hour service and you’ll see oil pressure climb faster on ignition, hear a quieter top end, and know your investment is protected for countless hours offshore. Quick to fit, built to last, and tuned by Yamaha engineers to keep your outboard running like new.
