2004 SN Limited. What are your thoughts? When I winterize I always have done it in my driveway but the engine never really gets up to temp while idling. We are going to pull the course this week and I will drain/change the oil at our site so it is good and toasty. Now, I won't winterize for another week or two hoping for one last ride in the large body of water (Sandusky Bay) if we get a warm day. Is it OK to run the boat for one last hour or so then complete the winterization process. Maybe a stupid question but just had to ask.
