Keihin Yamaha identification

[YARGESOL]

Greetings,cruisers! I'm cleaning & tuning my outboard Yamaha F20 carburator.
This is BCM Keihin 6AH00 W102 - all what's shows. How to determine the model of the carburator, in order to get a repaire kit ? Youtube video reccomends:" Check the Keihin logo - to be sure that this is original Keihin, note the serial no and,call the dealer". My Yamaha had visited few repair shops from Florida to Spain. Recently, I found one gasket (was convicted in Bermuda) still in same conditions - cracked. I would like to do this jobe better myself, like in a blessed time, when I was cleaning my Lada carburator's jets or
adjusting the ignition in the field. There are no dealers at the anchorage... There is plenty of kits at amazon/ebay but, mostly for motos.
Thanks
