Are you getting a full flow of fule to the carburetor> Seems like you may have enough for idle but not enough for horsepower, test would be a line from fule pump into a separate fuel container.

Having a problem with 15 hp 4 stroke Mercury engine. Checked fuel line from gas tank, filter, fuel pump, rebuilt carb. Has adequate fuel flow. When testing engine today it accelerated at first but then would not after a few minutes. Need more trouble shooting tips?
Expert:  Curtis B. replied 7 months ago.
Can you run it from another tank, direct to the fule pump? I still think there is fuel starvation. It has the fuel to begin with, but is being restricted when t will not accelerate.
Customer: replied 7 months ago.
We have tried different fuel tanks
Expert:  Curtis B. replied 7 months ago.
Have you used a different fuel hose from tank to carburetor?
Customer: replied 7 months ago.
Yes
Expert:  Curtis B. replied 7 months ago.
Could the exhaust port be plugged?
Expert:  Curtis B. replied 7 months ago.
If exhaust can't get out, fule can't get in.
Customer: replied 7 months ago.
Ok will check that thanks
