Can someone show me in an engine manual or manufacturer info where it says to run them at least a couple times a month or any similar info? If your conditions warrant due to bottom growth or other items I can see it but otherwise I see no validity in starting them every other week. There are millions of boats, cars and other internal combustion engines that are winterized and/or not ran for months at a time. Now I'm not talking about letting something for years. As we all know, if it rests, it rusts. But starting every other week? How long do you really think the oil stays up in the engine after you run it? Have you never heard that the most destructive time for an engine is at start up until oil pressure builds? Why keep doing this? What are you gaining?
