Customer Question

I have a 2013 Mercury 30 hp 4 stroke. The engine cranks and runs at about half throttle but sputters when I increase the throttle. Engine doesn't die just runs at a low rpm and feels like can't get gas. What is wrong?

Hello, my name is***** you for allowing me to assist you today.

Has the engine been sitting for some time?

How is the oil level?

Portable tank or installed?
Customer: replied 1 year ago.
Has been sitting for about 6 weeks. Has a portable gas tank.
Expert:  Charles replied 1 year ago.
First thing is to make sure that the vent is open on the tank.

Then check the fuel for water. It is really easy to buy water at a gas station.

Does squeezing the primer bulb over and over help the motor sped up?

The vent cap is open. Really doesn't help to squeeze the primer

Can you get a sample of the fuel that is in the tank?

Put it into a glass jar and see if there is more than one layer in the jar after allowing it to settle for a few minutes.
