I have a 2002 Sundowner 205 with a 5.0 GL VP drive train. I put together this checklist to help me winterize my boat each year. I do store it inside so I don't have to shrink wrap it. I take my time and this takes me about four hours. I did buy an oil extractor and an antifreeze winterization kit from Westmarine. You also need a set of muffs for the stern-drive. Beyond that no other special tools are required. Paste this into Word so you can take it to the boat and mark things off as you go through the process.
