Yamaha Connecting Rod Plain Bearing – SKU 6S5‑11656‑60‑00

Inside every Yamaha four‑stroke, these small half‑shells shoulder huge loads. This genuine plain bearing slips into the big end of the connecting rod, forming a low‑friction film between rod and crank so each piston stroke stays smooth, cool, and efficient.

• Tri‑metal build: steel backing for strength, copper‑lead core for heat transfer, and a micro‑thin polymer overlay that resists scuffing at high RPM
• Factory oil‑groove geometry: matches the crank journal’s feed holes, guaranteeing a steady oil wedge even at idle
• Micrometer tolerances: bored to within 0.01 mm for F225, F250, and other 6S5‑series V‑6 outboards—no sizing or shimming required
• Color‑coded edge stripe: quickly confirms bearing grade when you’re balancing clearances during a rebuild

Swapping a tired bearing before it flats out prevents crank scoring, hot spots, and the costly domino failures that follow. Whether you’re freshening up a high‑hour motor or buttoning up a full overhaul, this OEM shell restores the silky rotation Yamaha engines are known for. Install it with assembly lube, set torque to spec, and head back to the water confident your powerhead is turning on a perfectly cushioned pivot.
