another motor problem

I have a 1989 force 85hp outboard. The motor runs good when its cold but once its warmed up it doesn't run well at idel and stalls every time i put it into gear. After im able to get it into gear with out stalling it sputters a little until a certain rpm then runs fine. Any ideas what the problem could be?

Re: another motor problem

Carb issue? I had a small outboard that did that a while back.. I almost had to rev it when I put it into gear to avoid that RPM range where it would stall.. Pretty sure it ended up being a carb issue but that was a few years ago..

Re: another motor problem

It could be a carb problem but the first thing I would do is replace all the old fuel lines with new hose. Include the small hoses on the motor. Clean the filter.

Then I would add Sea Foam to the tank and run it through. I use Sea Foam in all my motors. The stuff cleans up the carb and it works.

There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.

You can but I have never done that. I just add it to the tank.

There are instructions for "direct induction" on the bottle.

Re: another motor problem

I had a similar problem years ago on a 15 merc would start and idle great but when put in gear it wanted to die. Took it for service and they put a new carb on it for me to test, it still did it. Ended up being a $2.00 set of reeds on the bottom end. Cost me $150 in labor to have them replace the reeds. Problem solved.
