I have a 2001 Yamaha F100A four stroke outboard. It was serviced just before the end of 2015. We have since had problems with water in fuel and fouled carbs. Water problem has been remedied and I have stripped the carbs and cleaned and serviced. I took it back to the Yamaha service shop to be synced and balanced, only to find that the Fuel Enrichment Valves are leaking at the top and need replacement O-rings. Yamaha Parts advise that there are no O-rings available as a spare part and will need to replace the entire Valve!!!!!$$$$$$
I am amazed at how Yamaha can do this as a cost of about $350 each instead of supplying a 30 cent O-ring!
Does anyone know the size of the O-rings (top cap) or a source of these to replace??
