Remanufactured by OBR in Alabama.

The cylinder head, camshaft, rockers, valves, and other internal parts are inspected and certified to be within factory specifications before re-use; otherwise, they are rejected. All bearings, seals, and gaskets are new.

Cylinder heads are carefully inspected & measured, and mating surfaces out of spec are re-surfaced if they can be done within OEM specs, otherwise, they are also rejected. Valves are carefully inspected, as are related parts, then resurfaced, seated, and preliminary adjustments done. OBR has decades of experience rebuilding outboard powerheads, and you can be sure of thorough and professionally rebuilt heads for your Yamaha!

4-Stroke cylinder heads ship via UPS or FedEx. These cylinder heads carry a 1-year warranty. Necessary gaskets are included.

Here's a picture from our tour of the facility in November 2016 of a group of cylinder head ready for use, after being cleaned, inspected, and any necessary milling. These pictured are 2-stroke, but 4-stroke heads are similarly treated, and then go on to have the internal components installed and adjusted.
