With my fuel tank replacement project delays I ended up winterizing my boat on a chilly day. I couldn't get my 2QM15 to start for love or money. I got some antifreeze into it by just cranking the starting battery to death...about half the normal volume...but I haven't been sleeping well. It hit 45 yesterday so I took the freshly charged battery and was finally able to get her started and properly flushed. We are getting some colder weather this week and it will be nice to sleep soundly
