Re: 1990 Evinrude 60HP VRO Idle adjustment
I've got a '91 60hp Evinrude and had some of the problems you're describing. Runs good in the yard but not in the water. Went through all the motions, ie, primer bulb, plugs, hoses, fuel pump, carb rebuild, etc. Come to find out my fuel tank had all kinds of trash and water in it. I took the tank out, put another one in with fresh gas and oil, cleaned the carbs again and runs like a champ in the water. Idles high in the yard, but does good in the water. Might be something to look in to.
