RAN FINE FOR 20 MIN THEN SHUT OFF TRIED TO RESTART IT FIRED AND STALLED THEN WOULD NOT FIRE AT ALL. I CAN NOT FIND A SERVICE MANUAL TO PURCHASE FOR THIS MOTOR 260, 5.7 EFI
What is the motor serial number?
Is it a new to you boat?
If not when was the last time it was running?
When the throttle is pumped does any gas squirt down the throat of the carb?
