Johnson 150 fast idle not shutting down even after 10mins at idle, what gives?

[SEASWIRL PAUL]

I have a year 2000 Johnson ocean pro v6 outboard. Prior to this year Ive never had this problem before. When I first start the outboard it goes into a fast idle or choke mode about 1200 rpms. When the motor warms up sufficiently it should shut off and idle at 7-900rpms. The only way I can get this "fast idle" mode to shut off is to put the motor into gear and idle up the channel. Then, after being in gear for a minute or two, she falls into a normal idle. I'm worried that 1. I could damage the newley replaced lower unit by putting it into gear at a higher rpm and 2. It runs (sputters)like hell until this fast idle shuts off.

Is there a connection I can lube?

Any feedback would be much appreciated.

Thanks, Paul

Seaswirl Paul, I had the same problem. You should replace the fast idle solenoide. It is located in a small well in the head. If you unplug it the idle will return to normal speed. Do not shift into gear under a fast idle.

It runs like hell because the Quick Start advances the timing until it heat up.* Here's how to check it.* Hope it helps.
