Re: 99 Johnson wont idle
Is this the same one that was overheating? Didn't you have a mechanic working on it? There are lots of reasons it might be having problems when cold. It could be something as simple as your starting and warmup procedure. Since you say it runs great after it's warmed up, maybe you should review the proper starting procedure once more, then let the thing warm up before heading away from the dock. Does it idle OK after it's warmed up? Does it run fine at all throttle settings?
Did this start after the mechanic worked on it? If so, go back and check with him.
I don't know your specific model at all, so that's about as far as I can go.
