How to Adjust Idle Suzuki 115hp (DF115)
How do I alter the engine idle to run faster or slowly while disconnected from a load? My 2003 Suzuki 115 hp outboard engine is running a little bumpy and irregular. The motor seems to run too slowly in neutral.
I suppose it runs too slow while out of gear and that is why it is running rough. I want modify the idle adjustment screw so that I can make it run smooth and balanced. How do I fine-tune the idle and where is the idle screw located? What is the stock idle rpm set at?
My boat motor is a 2004 Suzuki 115 hp 4-stroke 119.0 cubic inch 4-cylinder electronic fuel injection engine.
