Hi,

I'm new to the site and have a question that I hope somebody can help me with. I just recently acquired an engine for another project and I don't know any information on this engine. It is just the engine. The only #s on the engine are Y643-010431 .

Can anybody help?

Thanks

Mike

It's a Yamaha 643 from a '72 or '73 model.

Thank you.

Is this a good engine?

Are parts available?
