I have a 1980 80hpmercury outboard that's now on my 24' pontoon boat. Have replaced a few things to get her running. Throttle cable being one of them, what rpm should I be idling at?
The correct idle speed is the slowest it will idle in gear, in the water w/o stalling. Normally that is about 850 in the water in neutral. Adjust the idle stop to that RPM, and adjust the throttle cable to push the throttle to the idle stop.
