2008 4.3 mercruiser carburetor

Hello, yesterday I was riding the boat and it die like no gas, can't turn on again. Motor cranking but not fire up. Still have more then 1/2 tank. Could be the electric fuel pump??

Sure, but it could be other stuff as well. Does your motor have a carb or some sort of fuel injection?

Do you have any spark?

If no spark, check the shift interrupt switch on the shift cable, at the motor. When you shift, the ignition is killed momentarily. They can stick, and you have no spark.

It's a carburetor and I didn't have time yet to check everything, I will be off tomorrow and if the weather helps I will check the sparks. Thank you for the help.

Have to ask…what about the safety lanyard maybe being to blame ? Obvious answer for sure.
Other than that, if it’s a carb, at that age, it will likely be a tks. Have a look up and search for the common issue these suffer with the enrichment solenoid sticking.

Ok couldn't wait for tomorrow, kkk check the spark and is good, git my new fuel pump and changed and it's starting now.
Now my question is, if the fuel pump is feeling the boat will beeping??

Not if it’s a carb, I’d say. Very few things that make an alarm on the carb engine. Most common thing would be low gear oil
