Yamaha 55 electric start outboard

[JOHN O'LEARY]

I have just bought a Yamaha 55 - BE - 663 - L310137 outboard engine. Could anyone tell me from these details what year this engine is so as I can buy a suitable manual? Any suggestions for the manual? JOL UK

A Model 663 is a '74 - '79 55hp.<br />

<br />If you can read a letter where the red arrows point, you can identify the engine more precisely:<br />Y='74<br />X='75<br />W='76<br />V='77<br />U='78<br />T='79<br /><br />Info is from the Modellguide
