View Full Version : Johnson shuts off

08-22-2009, 01:47 PM
"I have a 1998-115 60 degree engine that won't stay running, shuts off in less than 1 minute.

Things I have done:

Replaced the powerpack.
rebuilt the carbs.
Switched to external fuel tank with pre-mix and clear hose.
Disconnected VRO harness.
disconnected the temperature sensors.

While running it looks the pump is not picking up fuel but squeezing the primer bulb doesn't help, the motor still dies. Pulled the drain plugs from the carbs after dieing, the carbs are full.

Does this motor have a kill circuit that might be triggering because of the VRO or something else? Does the ignition rely on a pulse from the VRO for continue running? Maybe,'Crasping at straws'...

Subscribed to Seloc manuals, they %^&*(, the wiring diagrams are NOT complete.

Does anyone have a clue?

Thanks in advance."
