Yanmar Head Screw

A genuine fastener. On a marine engine the right grade, thread and corrosion resistance matter — fit the correct original part and renew any fastener that's stretched, seized or corroded.

This is the genuine Yanmar Screw (part number 165000-70170).

Genuine OEM part, despatched from our Melbourne warehouse — prices include GST.

30-day no-fuss returns. If you opened the box and the part doesn't fit, send it back unused within 30 days for a full refund. We'll cover return freight on our error; you'll cover it if the part was correct as ordered.

12-month warranty. Manufacturing defects covered for 12 months from purchase date. Wear-and-tear (impellers degrade with use — that's their job) is not covered, but reach out if something fails early and we'll work it out with the manufacturer.

Australian Consumer Law applies in addition to the warranty above.
