I just read BigC's post on needing help with his 60 hp Merc. If ethanol eats the inside of the primer bulb and fuel lines isn't Sta-Bil or Seafoam supposed to correct the ethanol problem? My friend Josh just had the EXACT problem and replaced the line and bulb and it runs fine. He uses Sta-Bil religiously and I use Seafoam; is one better than the other?
