I came across a new Yamaha powerhead over the weekend and am unable to identify it. It is in the original crate from Yamaha but the part number tag is gone from the crate. It is a V-6 2 stroke. There are several stampings on the block but I cannot find a web site that breaks them down. Does anyone know of one? Some of the numbers are 6R500 and 6R300. I would appreciate any help. Thanks in advance.
