Hi Guys,I am new to this forum to be honest I belong to a small boating club here in Kent uk. and i get called upon to help out with mechanical/electrical problems for other members and if I can help I will. I am a retired auto electrician so do know a little bit,and always willing to learn.
Helping a member to get his Yamaha 20 running but would like to know when the outboard engine was built. The plate No. 20a 657L30191 and the reason being is to know which manual to buy if there is one available .
I would appreciate any help on this matter.

We don't have any manuals or any information on that model available here in the USA.
