I have this 2000 Yamaha 150 w/ox66efi, it runs like a champ until it warms up... It is hard to restart after shutting it off and fishing a while...I had a pretty knowledgable guy tell me that the fuel mixture needs to be ritchened up??? Hard to do on computer controlled motor?? anybody have similar problems? what is the fix? I hate to think about the down time and expense at the dealer.
