I have a 1969 mercury 3.9 outboard motor and it will start and run for a few seconds then shut off. I can't get it to stay running for more than a few seconds. Any ideas.

Be sure to run the recommended fuel mix. most modern 2 stroke outboard engines run on 100 to 1, some times the mix is on a decal inside the cowl.

Started up my acura tl 2000 and started to hear knocking and shut off


Check oil level and oil pump. Oil pump light should turn off after a few seconds after start up. If light stays on for more then 3 second shut off and do not drive or run motor.

My mercury 9.8 hp 110 starts but only stays running at half choke


Sounds like it needs a fuel pump kit, and possibly also a carby kit.

take photos as you are pulling the fuel pump or carby apart, or get a service manual for the outboard. The dealer might photocopy the pages you need if you ask nicely.

Mercury outboard over charging


Your motor is fine. It needs to put out more than 12 volts or the battery will not charge. Most alternators put out between 13 - 17 volts, so this is well within the range.

Outboard motor won't run under load


I have 1969 5hp Johnson. Starts and runs good, but will only push a 14ft row boat slow at low to medium rpm. When at higher rpm the the motor just revs up and the boat slows down to almost nothing just like it has seaweed around prop.Any help would be great.
