Customer Question
I have a 2003...

I have a 2003 70 hp johnson outboard that starts and runs for about ten minutes then dies and wont restart

Mechanic's Assistant: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

I have checked the fuel system including the high pressure pump and it appears to be working correctly. When the motor dies i can restart with starting fluid

Got it. This engine is EFI. There really isn't anything you can do yourself without a scan tool/EV Diagnostics. The engine really has to go to the dealer. Was there something I could help you with?

It might work for 10 seconds or 3 months before it stopped again. Tapping directly on the relay does not work. Tapping lower on the engine mounting bracket does not work. It never stops working while it is moving. … read more
