I'm hoping someone alot smarter than me can help me with this. I have a 2001 Evinrude 200 Ficht. When I nudge the throttle into idle or slow trolling position, the engine will rev from below 1000 rpms quickly up past 3500 rpms or until I back down off the throttle. If I don't back off, the rpms will want to keep climbing. It only does this when I try to throttle it at idle or trolling speeds. And this problem seems more prevalent when the boat is out of the water and I'm running the engine hooked to a garden hose. To keep the rpms from revving too high too quickly, I have to constantly adjust the throttle. Does this sound like an engine problem to you or could I just be having throttle cable issues? Anyone have any experience with this type of problem? Thanks.
