I have a Honda BF75 carbed outboard. I always use the carb drains when winterizing but would like some advice on how long I can leave the boat in season without having to drain the carbs. The manual just states how to drain them not any time intervals. I use non ethanol fuel and fuel treatment. Most of the time I would say the interval is about 2 weeks when it might sit. Sometimes the interval will change due to circumstances and draining the carbs, while not all that bad, is a pain.
