A friend has a 2007, 8 hp Yamaha 4 stroke that won't run at a trolling speed of about 2 mph. It'll do fine at idle and if you pass the 2 mph it's fine too. What's should we be checking out here?

Thanks​
 
Carburetors plug up very easily if fuel is left in them for extended periods.-------------Clean the carburetor, usually no new parts / money required.
 
I was thinking down those lines, but wanted to hear it from someone who's around these things more than I am. I appreciate the help Racerone.
