I have a 1984 charger boat with a 120 johnson VRO V4 dont know the year of the motor, the mod# is J1A0TLC0 and the ser# G&Q27834. the VRO system has been removed and i mix the gas in the main tank. The last owner let the boat set for awile. After reparing the stering cabel and having the motor worked on it runs great. I took it out on Saturday and ran it for about 1 and 1/2 hrs without a problem. On my way back to the marina it died???. I lifted the back hatch and discovered that the primer bulb was compressed. no gas was getting to the motor, very strange. I remover the gas line at the tank and the primer bulb went back to normal. started up and went about 1/4 mile and it happened again.after repeating the procedure about 6 times i made it back to the marina. any help on the year of the motor and the primer bulb problem would be very helpful.
