Since my boat has Honda outboards on it, I don't need to winterize them. Because of this, I like to try to start them every 2 to 3 weeks and let them idle for a bit to keep things internally lubed. Well, as typical, there's a problem - my port motor was blowing what looked like white smoke the entire 45 minutes the engine was running. There was no oil or anything else coming out the exhaust and the exhaust didn't smell like anything was burning abnormally. It was probably 45 degrees out during this event. I was thinking it was just the hot exhaust hitting the cool air, but the other motor wasn't doing it at all.
Could this just be a fluke due to the cold weather or do I have a bigger problem on my hands come the spring?
