Ok - after much searching i still have questions, I will try to explain, fully, the problem. I am new to outboards but am a mechanically inclined motorcycle tech.
Motor is a 1998 mercury 50 hp 2 stroke,
The problem is that the engine does not seem to want to run at "high idle".
When starting - lift high idle lever, push in choke button with key, turn key and she starts right up. Runs up the tach to wherever high idle lever is set. When warmed up she is ideling ok.
When running - the rpm wont go over 3000, even at WOT. It appears as if the engine is either flooding or being gagged. There is no sputtering or misfire, engine sounds fine and the tell tale is working (warm water, not hot, good stream). The interesting part is that when running at WOT and the tach is at 3, if you push the choke button in, the engine takes off, jumps up on the tach like it should and sounds completely different like it reaches a "high idle". Is there a selenoid or something that could be keeping the engine from reaching full potential or is this just as simple as a high idle needle jet in one of the carbs.
Was hoping someone could guide me before I start tearing into the carbs first.
Thanks in advance!!!
