Customer Question

I have a 2002 40hp mercury 4 stroke 3 cylinder that will start up and run for a few seconds then cut off. I recently just purchased the motor and the recent owner said it had been sitting up for a while. I replaced the fuel pump because the old one was locked up.
JA: 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. Is there anything else important you think the Marine Mechanic should know?

Are you able to rev the engine up in neutral?

Customer: replied 11 months ago.
I am not able to
Expert:  Jason replied 11 months ago.

Not able to as in your remote control will not allow for it, or not able to as in you tried, but the engine still stalls?

Customer: replied 11 months ago.
The engine stalls, the engine will only run for about 5 to 10 seconds
Expert:  Jason replied 11 months ago.

Are you near the engine now?

Customer: replied 11 months ago.
Expert:  Jason replied 11 months ago.

Pop the engine cover off. Go over to the carbs. Have a helper start the engine up, and then by hand open the throttle linkage on the carbs and see if it will stay running at a higher rpm.

Customer: replied 11 months ago.
There are no carbs on this engine
Expert:  Jason replied 11 months ago.

Hmmm.... Can you double check that serial number. A 2002 40 should be carbureted. I just went to run the serial and it came up invalid.

I'm trying to send you a picture but it will not let me

Oh, never mind
Customer: replied 11 months ago.
Isn't this the serial number?
Expert:  Jason replied 11 months ago.

Yeah that's the number. For some reason it doesn't take in Mercurys dealer network. Because it's fuel injected its' going to have to get hooked up to a scan tool. This doesn't sound like something i'm going to be able to help you out with here.

Ok, thanks for the help Jason.
Expert:  Jason replied 11 months ago.

You are welcome, good luck.
