I have never seen one like it before and I didnt recognise the model/serial number either. Its a bit of a mystery engine, finding parts is tricky.I don't know. That model number doesn't match the Yamaha model charts I can find, nor can I find any useful into on that model via a web search.
Thats a relief because Im in the UK!It is not a model sold in USA
