    I bought a 2008 Supra this year. I have never winterized a boat like this. Can I get some help?

    Greg, find a Supra forum online somewhere. The Malibu forum has a bunch of info on how to do it, so I would think that the Supra owners would do the same. In a nutshell, you need to get the motor up to operating temps some how (on the water, fake-a-lake or just shove a hose in the raw water intake), change engine oil, change tranny and v-drive oil, start the motor to circulate new oil and Sta-bil that you should have in the fuel, fog the cylinders (through the intake if you don't have cats or individually if you have cats), drain the block completely (pull knock sensors or drain plugs), drain exhaust manifolds, drain heater core if you have a heater, drain shower lines if you have a shower, pull your hull drain plugs, pray that you got all the water out. Some guys pull antifreeze in, but I agree with most in thinking that just promotes you to NOT fully drain the system. So, I'm not putting that in and running an Xtreme bilge heater just for the piece of mind.

    Brian pretty much nailed it for a full winter lay up. At a shop we would drain all he listed, AND fill it all with RV antifreeze. Make sure all the ballast lines and pumps are drained and filled with antifreeze. The problem with draining only is water can get caught in areas that don't drain well or low points in the systems. Also, when draining the system make sure water drains from every drain point. If you pull a plug and nothing comes out , its not empty, its clogged. Stick something in it to break it free. I use a piece of bailing wire and or a guitar string. Take your time and do it right, but once you figure it out and know your systems, you can do it fairly quickly. If you want to be able use your boat all winter, I suggest draining after each use and using a bilge heater. Use an extension cord that lights up on the end, so you can easily see the heater has power. Hope this helps, Adam

    I just did a trial run yesterday and was able to fully drain my setup (put 4 quick disconnects in my system) in about 5 minutes. My heater has it's own extension cord, so I'll need to buy one of those plugs with the light built it. I plan on running mine until Thanksgiving and probably put it back into the water in March/April.
