So I will be pulling my boat out here in a few days and of course have a list of things to do before hitting the water. It is a 2011 250 pro xs. I thought I had read earlier that there are gaskets that needed to be replaced when you remove the thermostats, but I can't seem to find that thread. This is my first Merc, so I am learning, but slowly! Thanks if anyone can chime in!
