How to Adjust Idle Yamaha 200hp?
How do I tune the idle on my 2008 Yamaha 200 horsepower 2-stroke, 76°, V6, HPDI outboard engine? The motor seems to run too slowly and sputters at trolling speed and it idles rough when it is out of gear. When the engine ticks over in neutral position it repeatedly stumbles. When I gun the engine sometimes it hesitates and acts like it’s going to stall momentarily before taking off.
