What idle speed is too high for a Bravo
I am having some issues getting my idle down below 900-1000 RPM. I think I have something binding in the throttle plate - maybe needs new bushings. It runs and idles fine, and I can press down on the throttle lever at the carb and it will idle down to around 800 RPM where I want it, but as soon as I use the stick to rev it up at all, when I pull the stick down it stays around 1000 RPM. Obviously I am going to keep working to correct this issue, but how much of a chance am I taking with it damaging the clutches on my drive if I shift at 1000 RPM?

I am going to take the advice and disconnect the linkage. I can press down on it and get it to sit on the throttle stop, and it idles fine at around 800. I guess I need to determine if the problem is in the carb linkage or the boat throttle linkage. Thanks for the replies - I will post an update.

The throttle lever is resistant to move from carb idle speed screw. Throttle lever also has a stop and cable is solid.Gas pedal in a car has no issue moving and stranded cable sometimes has slack and can bend with no effort. Thus why you must follow procedures most of us have detailed.
