Help!! I have a Yamaha 200 hp ox66 motor 2004 with the throttle body type injection. Engine ;will start once when first starting, kill and then will restart and run fine. (not sure if this would have any bearing on concern). engine runs fine until it is shut off and sits for anywhere from 20 minutes to an hour. Sometimes it will start and run ok, other time will not start and the primer bulb has no fuel so must be pumped. I have had this to 2 dealers with no positive results. All 3 low pressure fuel pumps have been replaced. Engine checked for compression and good across the board. Had a tournament this weekend and had to come in on the trolling motor as the engine would not start even when the bulb was pumped full. Got home and tried to start, started up with no problem. Anyone have any knowledge about this concern???
