I did some work on my boat recently (impeller, thermostats, carb cleaning, etc.). Motor is a '04 Yamaha Vmax 150 HP. (FYI, I ordered a new fuel filter and will be replacing that in a few days, just to keep up proper maintenance.)
For the most part it runs fine, but... I think it is idling too low as it will die from time to time while just idling on the lake, or after just getting to warm up after initial start. It never dies while actually in gear and running, just at various times while idling. It is very quiet in the water, but it just sounds like it idles too low. How do I go about setting it to idle properly? Do I need to adjust as per proper RPM setting, or sound, or what?
