High-idle RPMs

[RIROCKHOUND]

Hi all:
Was out today in our 25ft r/v with a 200hp Opti SW series...
Just changed the fuel/water separator, and got a fresh tank of gas..

Engine is 'surging' at idle, basically running at a much higher rpm than normal. Operation seems great at top end, but at idle it is revving way too fast. also seems a tad rough at low survey speeds (3-5kts)

Thanks
Bryan

From what it sounds like your fuel/water separator would be the culprit. It was probably not getting enough flow through it. I would simply adjust the idle and you should be good to go.
