I have a friend that has a 90hp force outboard. It will start and run not bad when cold, however after it has run for about 5 - 10 minutes it idles fine but when you try to put it in gear it dies out. You can put it to fast idle no problem.<br /><br />It has been to the boat repair shop and they cleaned the carbs and resync'd the carbs but still no difference.<br /> <br />When it is warm it just is a royal pain in the butt.<br /><br />Once it is in gear and stays running it seems fine. The idle speed is ok. When it was in the shop the spark plugs where replaced and the compression checked.<br /><br />Any suggestons - Did these engines have electronic module issues? That is about all it can be that I can think of.<br /><br />Thanks for any help.<br />My friend is about at the stage to take it for a run with the plug out of it.
