[zaria123]

Hi Folks
Is anyone able to help me identify the age and spec of this yamaha outboard engine with serial number:
On the vin plate YAMAHA 4AC 6LO L 347877
Any help would be highly appreciated.
Thanks
Alan

We don't have any information on engines sold outside the USA and that model number doesn't match any models we have.
